"Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions."
This subfield studies the rates and mechanisms of chemical reactions.
Reaction rates: The study of how fast chemical reactions occur and the factors that affect the rate of a reaction.
Reaction mechanisms: The step-wise sequence of chemical reactions that occur during the course of a reaction.
Rate laws: The mathematical expression that relates the reaction rate to the concentrations of the reactants.
Elementary reactions: The individual steps of a reaction mechanism that involve the collision of molecules.
Temperature dependence: How the rate of a reaction changes with temperature due to the effect on reactant particle collision frequency.
Activation energy: The minimum amount of energy required to initiate a chemical reaction.
Reaction order: The sum of the exponents of the concentrations in the rate law.
Integrated rate laws: Expressions that describe how reactant concentrations change with time for a given reaction.
Reaction kinetics in the gas phase: The study of chemical kinetics in gases and the application of gas-phase reaction kinetics to atmospheric chemistry.
Enzyme kinetics: The study of the rates of enzyme-catalyzed reactions and the factors that affect enzyme activity.
Auto-catalysis: A type of kinetic reaction where one of the products in the reaction acts as a catalyst for the reaction.
Homogeneous catalysis: A type of catalysis where the catalyst and reactants exist in the same phase.
Heterogeneous catalysis: A type of catalysis where the catalyst and reactants exist in different phases.
Photochemistry: The study of chemical reactions that are initiated by light.
Electrochemistry: The study of chemical reactions that involve the transfer of electrons.
Reaction dynamics: The study of the motion of atoms and molecules during a chemical reaction.
Kinetic modeling: The development of mathematical models that describe chemical reactions and their kinetics.
Rate-determining step: The slowest step in a reaction mechanism that determines the overall rate of the reaction.
Inhibitors and catalysts: Substances that slow down or speed up a chemical reaction.
Quantum tunneling: A type of kinetic reaction where reactants can cross an energy barrier without having enough energy to overcome it.
Elementary reactions: These reactions occur in a single step and involve a single reactant molecule. They are usually described by rate laws that depend on the concentration of the reactant.
Complex reactions: These reactions occur in multiple steps and involve multiple reactant molecules. They are usually described by a series of elementary reaction steps, each with its own rate law.
Homogeneous reactions: These reactions occur in a single phase (either gas, liquid or solid) and involve reactant molecules of the same phase.
Heterogeneous reactions: These reactions occur between reactant molecules of different phases (for example, a gas and a solid). These reactions are often influenced by factors such as surface area and temperature.
Photochemical reactions: These reactions are initiated by the absorption of light energy and are often used in the study of organic chemistry and environmental science.
Enzymatic reactions: These reactions are catalyzed by enzymes and are important in many biological processes.
Oscillating reactions: These reactions exhibit periodic changes in concentration or other properties over time.
Autocatalytic reactions: These reactions involve a product that acts as a catalyst for the reaction.
Radical reactions: These reactions involve the formation and reaction of reactive intermediate species called radicals.
Acid-base reactions: These reactions involve the transfer of a proton (H+) between reactant molecules.
