The branch of chemistry, which deals with the study of reaction rates and their mechanisms, called chemical kinetics.
Thermodynamics tells only about the feasibility of a reaction whereas chemical kinetics tells about the rate of a reaction.
For example, thermodynamic data indicate that diamond shall convert to graphite but in reality the conversion rate is so slow that the change is not perceptible at all.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Objective:
Prepare a presentation or a paper using research, basic comparative analysis, data organization and application of economic information. You will make an informed assessment of an economic climate outside of the United States to accomplish an entertainment industry objective.
1. Solutions
Colligative Properties
• Changes in colligative properties
depend only on the number of solute
particles present, not on the identity of
the solute particles.
• Among colligative properties are
Vapor pressure lowering
Boiling point elevation
Melting point depression
Osmotic Pressure
2. Solutions
Vapor Pressure
Because of solute-
solvent intermolecular
attraction, higher
concentrations of
nonvolatile solutes
make it harder for
solvent to escape to
the vapor phase.
5. Solutions
Boiling Point Elevation and Freezing
Point Depression
Nonvolatile solute-
solvent interactions
also cause solutions
to have higher boiling
points and lower
freezing points than
the pure solvent.
6. Solutions
Boiling Point Elevation
The change in boiling
point is proportional to
the molality of the
solution:
Tb = Kb m
where Kb is the molal
boiling point elevation
constant, a property of
the solvent.Tb is added to the normal
boiling point of the solvent.
8. Solutions
Freezing Point Depression
• The change in freezing
point can be found
similarly:
Tf = Kf m
• Here Kf is the molal
freezing point
depression constant of
the solvent.
Tf is subtracted from the normal
freezing point of the solvent.
9. Solutions
Boiling Point Elevation and Freezing
Point Depression
Note that in both equations,
T does not depend on what
the solute is, but only on
how many particles are
dissolved.
Tb = Kb m
Tf = Kf m
19. Solutions
Colligative Properties of Electrolytes
Since these properties depend on the number of
particles dissolved, solutions of electrolytes (which
dissociate in solution) should show greater changes
than those of nonelectrolytes.
20. Solutions
Colligative Properties of Electrolytes
However, a 1 M solution of NaCl does not show
twice the change in freezing point that a 1 M
solution of methanol does.
22. Solutions
van’t Hoff Factor
Some Na+ and Cl− re-
associate for a short time, so
the true concentration of
particles is somewhat less
than two times the
concentration of methanol.
23. Solutions
The van’t Hoff Factor
• Re-association is more likely
at higher concentration.
• Therefore, the number of
particles present is
concentration dependent.
24. Solutions
The van’t Hoff Factor
We modify the
previous equations
by multiplying by the
van’t Hoff factor, i
Tf = Kf m i
25. Solutions
The van’t Hoff Factor
Determine the expected boiling point of a solution made by
dissolving 25.0g of barium chloride in 0.150kg of water.
