Ahl kinetics
Here is a 1 page summary explaining the link between reaction order and mechanism:
Reaction mechanisms involve multiple elementary steps where molecules interact to form products. However, the overall rate of reaction is determined by the slowest step, known as the rate-determining step (RDS). The order of the reaction provides clues about which elementary step is rate-determining.
For example, consider the reaction:
A + B โ C
If the reaction is first order with respect to [A], it suggests the RDS involves the collision and bonding of only A molecules. The formation of the A-B complex must be fast compared to this bond formation.
However, if the reaction is second order with respect to [
Lipids (2)
Lipids are organic molecules with long hydrocarbon chains that are soluble in non-polar solvents. They serve several important functions in the body including energy storage, insulation, forming cell membranes, and acting as hormones. The most important types of lipids are triglycerides, phospholipids, and steroids. Phospholipids make up cell membranes while cholesterol is transported around the body by lipoproteins, which can either deposit or remove cholesterol from arteries. Certain fatty acids, such as omega-3 and omega-6, are essential as the body cannot synthesize them.

8 d ecological relationships
The document discusses several key concepts relating to ecological relationships:
1) It defines an ecosystem as all the organisms living together as a community in a particular habitat.
2) Ecosystems are constantly changing due to physical factors like temperature, as well as changes in populations from predation, disease, pollution, and human interference.
3) To measure changes in an ecosystem, scientists use sampling techniques to analyze the physical conditions of a habitat and populations of different species within that habitat.
Titrations
Solution stoichiometry uses molarity to relate volume and moles of substances in solutions. Titration is a technique to determine concentration of a solution by measuring the volume of one solution needed to completely react with another. In titration, the analyte of unknown concentration reacts with a titrant of known concentration until the equivalence point is reached, as indicated by a color change from an indicator. Calculations involve determining moles of titrant added and relating it to moles of analyte to find the analyte's original concentration.
8 c microbes and disease
This document provides an overview of microbes and disease. It defines microbes as very small living things that can only be seen with a microscope. There are three main types of microbes: bacteria, viruses, and fungi. The document describes how each of these microbes can cause disease when entering the body, and how they are spread through various forms of transmission, such as through the air, water, animals, and contact. It also discusses how the human body and treatments like antibiotics fight off microbes and disease.
Y10 airwater

It also covers properties of liquids related to intermolecular forces like surface tension, viscosity, and water's unusual properties. Finally, it discusses phases of matter, phase transitions, vapor pressure, boiling/melting points, and heat effects of phase changes.
Benzene story
Here are 3 key problems scientists faced in explaining the structure and bonding of benzene:
1. Benzene did not react like a typical alkene as expected based on its molecular formula.
2. The thermodynamic stability of benzene was greater than predicted if it contained alternating double and single bonds.
3. The carbon-carbon bond lengths in benzene were equal in length, inconsistent with alternating double and single bonds.
Through continued experimentation using new techniques like STM and theoretical developments like valence bond theory, the current understanding of benzene emerged. Scientists now recognize that benzene's electrons are delocalized through conjugation into a ring above and below the nuclei. This explains benzene's extra stability and
Respiration
1. Respiration is the process by which living cells produce energy from food. It involves the reaction of oxygen with glucose or other carbon-containing compounds to produce carbon dioxide, water, and energy.
2. Aerobic respiration uses oxygen to completely break down glucose into carbon dioxide and water, releasing more energy. Anaerobic respiration breaks down glucose without oxygen, producing less energy as well as alcohol or lactic acid.
3. Anaerobic respiration occurs in muscle cells during intense exercise when oxygen is in short supply, and in yeast and bacteria during fermentation processes like winemaking, brewing, and bread rising.
8 e atoms and elements
1) Atoms are the building blocks of all matter and are made up of protons, neutrons, and electrons.
2) Elements are substances made of only one type of atom, while compounds contain different types of atoms bonded together.
3) Some common elements and their symbols include hydrogen (H), helium (He), carbon (C), oxygen (O), sodium (Na), iron (Fe), copper (Cu), and silver (Ag).
Enzymes IBDP HL
Enzymes are protein molecules that catalyze biological reactions. They work by lowering the activation energy of reactions, allowing more molecules to react. Enzymes are highly specific and their tertiary structure forms an active site that binds substrates. Inhibitors can bind the active site and prevent substrate binding (competitive) or bind elsewhere and alter the enzyme shape (non-competitive). The rate of enzyme reactions saturates at high substrate concentrations as active sites fill.
Nutrients (2)
The document defines micro- and macro-nutrients. Micro-nutrients are required in small amounts and include vitamins and minerals, while macro-nutrients such as proteins, fats, carbohydrates and minerals are needed in larger quantities. It then discusses the characteristics and roles of specific vitamins like A, C, and D. The text also covers malnutrition which can occur due to deficiencies or excesses of micro- or macro-nutrients, and lists some deficiency diseases and their symptoms. Finally, it proposes solutions like eating fresh nutrient-rich foods, fortifying staple foods, genetically modifying crops, and using supplements to combat malnutrition.
Carbohydrates (1)
Carbohydrates can be classified as monosaccharides, disaccharides, or polysaccharides depending on their size. Monosaccharides like glucose are the basic units that combine to form larger carbohydrates. Disaccharides contain two monosaccharide units joined by glycosidic bonds, such as sucrose. Polysaccharides are long chains of monosaccharides and include starch, glycogen, and cellulose. Carbohydrates serve important functions in the human body by providing energy, storing energy in the form of glycogen, and acting as dietary fiber for digestive health.
G11 s lequilibria
The document discusses the position of equilibrium in chemical reactions. It states that if a dynamic equilibrium is disturbed, the position of equilibrium will move to counteract the change according to Le Chatelier's principle. Specifically, it provides examples of how the equilibrium position would change if ammonia, hydrogen, or nitrogen were removed from the ammonia synthesis reaction, or if pressure or temperature were increased. It also notes that while catalysts speed up the rate of the reaction, they do not change the equilibrium position.
G12 sl humanbiochem
This document provides an overview of human biochemistry, covering topics like energy metabolism, proteins, carbohydrates, lipids, and micronutrients. It discusses how humans derive energy primarily from the oxidation of fats, carbohydrates, and proteins. Proteins are natural polymers made of amino acids, with essential amino acids that must be obtained through diet. The structure of proteins is described from primary to quaternary levels. Proteins serve important roles in the body such as structural functions, catalysis as enzymes, and transport. Electrophoresis techniques can separate amino acids based on differences in their isoelectric points.
Energetics1
The document defines standard enthalpy change, exothermic and endothermic reactions, and signs for exo/endothermic reactions. It provides examples of enthalpy calculations, experiments to determine enthalpy changes, and defines combustion enthalpy, formation enthalpy, and Hess's law.

It provides study questions, examples to explain, and assignments to complete including drawing organic molecule structures and identifying optically active compounds.
Sl kinetics
1. The document discusses collision theory and how various factors affect the rate of a chemical reaction. It defines rate of reaction and lists collision frequency, number of particles with energy greater than or equal to the activation energy, and proper collision geometry as factors that reaction rate depends on.
2. It explains Maxwell-Boltzmann distribution and how increasing temperature, concentration, pressure, decreasing particle size, or adding a catalyst can increase the rate of reaction by altering the distribution.
3. It defines a catalyst as a substance that speeds up a reaction by providing an alternative reaction pathway with a lower activation energy, but is unchanged at the end and recovered in the same amount.
