This Perspective presents a personal overview of the current status of the theory of chemical kinetics and mechanisms for complex processes. We attempt to assess the status of the field for reactions in the gas phase, at gas–solid interfaces, in liquid solutions, in enzymes, and for protein folding. Some unifying concepts such as potential energy surfaces, free energy, master equations, and reaction coordinates occur in more than one area. We hope this Perspective will be useful for highlighting recent advances and for identifying important areas for future research.
The document discusses kinetics and the rate law for the decolorization of crystal violet. It describes using a spectroscopic colorimeter to monitor the concentration of crystal violet over time as it reacts with sodium hydroxide. The goals are to determine the overall rate law and rate constant k for the decolorization reaction. Experiments are conducted at different concentrations and the orders are determined by analyzing linear regression graphs of integrated rate laws versus time and concentration. The 1st order graph provided the best correlation, indicating the reaction is first order with respect to crystal violet concentration.
Here are the steps to determine the order of the reaction:
1) Plot [X] vs time on a graph. You will get a straight line through the origin, indicating the reaction is first order.
2) Take the log of both sides of the rate law equation:
Rate = k[X]
Log(Rate) = Log(k[X])
3) Plot log(Rate) vs log([X]). You will get a straight line with a slope of 1, confirming the reaction is first order.
Therefore, based on the experimental data and analysis, this reaction is first order with respect to X.
The half-life of N2O5 for a first order reaction is:
t1/2 = ln(2)/k
= ln(2)/(6.93 x 10-3 s-1)
= 100 s
So every 100 seconds, the concentration of N2O5 will be half of what it was 100 seconds earlier.
This document summarizes key points from Chapter 11 of Holt Modern Chemistry regarding Avogadro's law and relating the volume and number of moles of gases. It provides an example problem of calculating the number of moles of gas in 46.5 liters at 28°C and 2.75 atm by converting to STP conditions. The document notes how the combined gas law can be used to convert volumes to moles using the definition that 1 mole of any gas at STP occupies 22.414 liters. It also suggests developing a conversion factor or "multiplier" to more directly calculate moles without intermediate steps. Finally, it directs the reader to practice problems #40-52 at the end of chapter 11.
This document provides information on naming covalent compounds and acids. It discusses how to identify covalent compounds based on their composition and discusses prefixes used in naming them such as mono, di, and tri. Rules are provided for determining the order and modified ending of elements in covalent compound names. Examples of naming covalent compounds like CO, P2O5, and H2O are also provided. The document also discusses naming acids based on whether they contain halides, -ates, or -ites and the number of hydrogens added to match charge. It concludes with a comparison of naming conventions for ionic compounds, covalent compounds, and acids.
The document discusses acid rain, including its causes, effects, and how to simulate its effects in a lab experiment. It explains that acid rain is caused by sulfur dioxide and nitrogen oxide emissions from industrial activities and vehicles. Acid rain damages buildings, statues, and the environment by corroding materials and lowering the pH of lakes and streams. The lab experiment will test the resistance of quartz, marble, and granite to simulated acid rain using vinegar to see which material is least affected.
This document provides an overview of concepts related to solutions and solubility, including:
1) Key terms like solvent, solute, concentration, and their relationships as demonstrated through examples of dissolving salt in water.
2) How temperature and concentration affect solubility, and how to read solubility curves. Exothermic and endothermic processes are discussed in relation to enthalpy of solution.
3) Molarity calculations including determining molarity from mass, calculating moles from molarity and volume, and dilution. Net ionic equations and solubility rules are also covered.
4) Colligative properties like boiling point elevation and freezing point depression are explained in terms of vapor pressure
This document provides an overview of basic chemistry concepts related to naming and writing formulas for ionic compounds. It discusses:
1) How to name ionic compounds by writing the cation first followed by the anion with "-ide" ending, except for polyatomic ions.
2) How to write formulas for ionic compounds by ensuring charges are balanced between cations and anions using subscripts.
3) Special rules for writing formulas involving polyatomic ions and d-block metal cations, which can have multiple oxidation states requiring specifying the oxidation number.
4) How to calculate formula masses of compounds by multiplying the number of atoms of each element by the atomic mass and summing the products.
This document summarizes different types of chemical bonds: covalent bonds formed by shared electrons between similar atoms, ionic bonds formed by attractions between oppositely charged ions, and metallic bonds formed when atoms share a "sea of electrons". It also discusses polar covalent bonds that occur between atoms with some difference in electronegativity, and intermolecular forces like hydrogen bonding and London dispersion forces. Key terms like crystal lattice, formula unit, and lattice energy are defined in the context of ionic bonds.
The document summarizes a presentation about the periodic table given by Lisa Allen at Stonington High School. It discusses the early development of the periodic table by scientists like Cannizzaro, Mendeleev, and others. Mendeleev was able to organize the elements into the first recognizable periodic table based on their atomic masses and chemical properties. He even predicted the properties of yet-to-be discovered elements. The document then outlines assignments for students to create their own periodic tables and presentations on periodic properties.
The document discusses the early history and development of quantum theory, beginning with Max Planck's hypothesis that energy exists in discrete packets called quanta. It describes how this helped explain phenomena like the photoelectric effect. The document also summarizes Niels Bohr's early model of the hydrogen atom and its limitations, leading to developments like Louis de Broglie's proposal that electrons have wave-like properties and Werner Heisenberg's uncertainty principle.
1) In the late 1700s, new scientific ideas and improved technology allowed for better understanding of chemistry through experimentation and data collection. Laws of chemistry like conservation of mass and definite proportions were discovered.
2) In 1808, John Dalton developed an atomic theory to explain the laws of chemistry, proposing that all matter is made of tiny indivisible particles called atoms. Atoms of each element are unique and combine in simple whole number ratios to form compounds.
3) Dalton's atomic theory accounted well for the known laws of chemistry and provided a rational scientific explanation for chemical reactions and compositions. While some details were later updated, Dalton's core ideas formed the basis of modern atomic
This document summarizes key information about subatomic particles including protons, neutrons, electrons, isotopes, and ions.
Protons have a positive charge and are found in the nucleus. Neutrons have no charge and are also found in the nucleus. Electrons have a negative charge and are found outside the nucleus.
The number of protons determines the element. The number of neutrons can vary between isotopes of the same element. Isotopes are identified using hyphen or nuclear notation. To find the number of neutrons in an isotope, subtract the atomic number from the atomic mass.
The number of electrons in a neutral atom equals the number of protons. Ions have a different number of electrons than

2. Chapter objectives (lots!)
Identify factors that influence reaction rates
Calculate rate of consumption of a reactant or of
creation of a product from stoichiometry

data
Solve for the rate constant from time/rate data
Determine the instantaneous rate of a reaction
Create graphs to determine order of a reaction
Use the integrated rate law to determine
concentration at time t
Determine half life of a reaction
Determine the activation energy for a reaction
3. Didn’t we already figure out if a
reaction would run
spontaneously?
Remember the rule from
thermochemistry – spontaneous does
not mean fast! Just because a
reaction is energetically favored, does
not mean it will run in a reasonable
amount of time. Thermochemistry
takes into account the energy of the
products and of the reactants, not any
activation energy required to run a
reaction.
4. Factors that influence reaction
rates
Concentration – the more particles
bump into each other, the more likely
they are to react
Temperature – the more particles
move, the more they bump into each
other
Increasing surface area – powdered
aluminum is much more interesting
than a chunk of aluminum
Addition of a catalyst – determined
experimentally
5. Effect of a catalyst on activation
energy
Reactions can be
endothermic or
exothermic – either
way, a catalyst can
facilitate overcoming
the activation energy
“bump”
6. Simple stoichiometry
In the reaction: N2 + 3 H2 2
NH3, what is the relationship between
the rate of production of NH3 and the
rate of consumption of H2?
In any given amount of time, twice as
much NH3 is created as nitrogen gas
disappears. Its RATE of generation is
twice as great. Its rate of generation
is 2/3 that of hydrogen’s
disappearance.

8. Determine the rate law of a
reaction
First,
Notice that Zumdahl
only selects examples
of reactions that have
a good reason not to
run both ways.
Usually, it is that one
of the products is a
gas that escapes.
Thus, only reactants
are considered in
elementary kinetics.
Next,
Notice that we are
beginning with
decomposition
reactions, in which
there is only one
reactant. This means
we are only looking at
the rate of change of
one substance – the
product concentrations
are stoichiometrically
dependent on the
reactant anyway.
9. 2NO2(g) 2NO(g) + O2(g)
See page 551 for table of
concentrations as a function of time
The rate of change is going to be
defined as the change in
concentration over the elapsed time.
The instantaneous rate is graphically
the slope of the line tangent to the
curve. You will NOT have to calculate
the slope of that tangent yourself
when the graph is a curve.
10. “WRITE THE RATE LAW FOR THIS REACTION”
RATE = K[NO2]N
For the reaction
2NO2(g) 2NO(g) + O2(g)
This k is NOT the same k as we used in
equilibrium. Sorry!
N is an exponent – this tells us whether the
disappearance of NO2 is directly related to
concentration (n=1), exponentially related
(n=2) or not based on concentration at all
(n=0)
The concentrations of the products are not
included because the reverse rate of the
reaction is not significant in this case – in
fact, you will never need to consider an
equilibrium situation for these problems.
11. 2N2O5 (aq) 4NO2(aq) + O2(g)
Notice in this
problem, the oxygen
leaves – no worries
about the reverse
reaction
On page 557, Z has
cut to the chase – the
concentration of N2O5
and the instantaneous
rate are presented
together
As the concentration
doubles, the
instantaneous rate
doubles. No more
math required; you
know that the value of
the exponent is 1
rate = k[N2O5]n
Now plug in n=1, any
concentration of
N2O5, and solve for k
You can now find the
rate at any
concentration of N2O5
12. Sneaky sneaky Zumdahl…
Notice that on page 552, you get a big
gorgeous graph of the concentrations of all
the substances in this reaction as a function
of time. The tangents at specific points are
calculated for you
In a tiny table on page 553, you get the
rate/time data, but even that is not
instantaneous.
If you graphed the change of the
instantaneous velocities, you would get a
straight line – this means it is a first order
reaction, although Zumdahl never tells you
that.
In fact, he moves to a different equation

14. Reactions with two reactants
NH4
+
(aq) + NO2
-
(aq) N2(g) + 2H2O(l)
Notice that the N2(g) leaves.
Z provides initial instantaneous rates
from 3 different experiments on page
559.
Spend a minute reading the table –
see if you can reach any conclusions
without a lot of math about the
relationships between concentration
and rate for each reactant.
15. Need a hand?
Look at the initial concentration of
ammonium ions. Do you see how
experiment 2 and 3 are related?
Notice that the NO2- does not change
between experiment 2 and 3. This
means the change in the rate is
exclusively dependent on the ammonium
concentrations
Notice the difference between
concentrations in experiments 1 and 2.
Can you establish the exponent for each
reactant in the rate law now?
16. rate = k[NH4
+ ]n[NO2
-]m
The rate doubles as the concentration
of NH4
+ doubles. Therefore, n=1
The rate doubles as the concentration
of NO2
- doubles. Therefore, m=1
Now you can plug in any of the values
for one experiment and calculate k.
Calculating k from different initial
concentrations should NOT yield
different k values.
17. WHAT DOES IT MEAN

Due next class – Friday April 26
Also, read to the end of chapter
12, and come prepared to ask
questions or to solve problems!
21. Which data am I being given?
Initial concentrations and
rates
Concentrations and
time
In this case, look for
patterns that will tell you
if the exponent in the rate
law is a zero, 1, or 2
No additional calculated
values are necessary to
find the rate order
In this case, add 2 more
columns of data
Include 1/[A] and ln[A]
columns of data when
presented with
concentration and time
23. Using the inverse and the ln
A graph of [A] over time will be a
straight line for zero order reactions.
One other data set you will need is the
natural log of the concentration.
A graph of ln[A] over time will be a
straight line for first order reactions.
The third data set you will need is the
reciprocal of the concentration.
A graph of 1/[A] vs. time will be a
straight line for second order
reactions.
24. Graph each data set with time on
the x axis
The graph of [C4H6] is not a straight line.
This is not a zero order reaction.
The graph of the ln [C4H6] is not a
straight line. The reaction is not first
order for [C4H6]
REJECT the data set of ln [C4H6].
The graph of 1/[C4H6] is a straight line.
Therefore, the reaction is second order
for [C4H6].
25. Finding k
Rate = k[C4H6]2
The k is actually the slope of the
graph. To find slope, calculate y/ x
from your graph.
Alternately, pick two values off your
data table to calculate the slope from.
Visually, I used (0, 100) and
(5000, 400) and got k=.06
Z did it with the data points and got 6.14 e -

27. The integrated rate law
Take a look at page 562, equation 12.2
and at the AP “cheat sheet” page
ii, kinetics section.
Note that the form of the integrated rate
law on the cheat sheet is somewhat
different than in Z. It is only marginally
different.
This form of the integrated rate law is
only applied to first order reactions. If
you use it to work with zero or 2nd order
reactions, you will mess up!! The
lesson? Establish the order before you
28. Why is Zumdahl right this
time?
Zumdahl has organized his version of
the integrated rate law into y=mx+b
format.
Y= ln[A]
M = -k
X = time
B = ln[A]o
THAT is cool!
29. Integrated rate law for second
order reactions
Page 567, eq’n 12.5
Again, Z uses y=mx+b format, and the
AP cheat sheet does not.

31. Half life – not as simple as you
thought!
The traditional concept of half life – the
amount of time it takes for half of a
sample to convert to some other form –
is based on first order reactions only
In first order reactions, half life follows a
simple equation
T1/2= .693/k
This is NOT on the AP cheat sheet!
This equation was derived on page 565
using the integrated rate law for first
order reactions. Follow the logic, and
you can reconstruct it if you need it.
32. Half life problem – first order
See Z page 566
Solve for k
Solve for time to a particular
concentration
Solve for a concentration at a given
time
Plug and chug… not difficult, except
that you must use the right equations!
33. What you should notice about
that half life equation
This is NOT dependent on
concentration! To calculate specific
concentrations at time t, you will need
the initial concentration, but you do not
need it to calculate k or t1/2
34. Half life of a second order
reaction
t1/2 = 1/k[A]0
This is specific to second order
reactions. It is not on the AP cheat
sheet, but can be derived from the
integrated rate law for second order
reactions.
This IS dependent on initial
concentration.
Unlike simple first order half life, second
order half lives do not mean half the
material changes in a set amount of
time. For these reactions, each half life
takes twice as long.
35. So to quote
Zumdahl, “Spontaneous does
not mean fast.”
But time IS something that we can use
to learn more about a reaction, what
its mechanism is, and how it is likely to
proceed. We can calculate with it.
We can graph stuff.
