"Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions."
The study of the rates and mechanisms of chemical reactions and how to control them.
Reaction rate: Reaction rate is the measure of how fast a chemical reaction occurs.
Rate laws: A mathematical equation that describes the rate of a chemical reaction, in terms of the concentrations of reactants.
Reaction mechanism: The series of steps or sequence of events that occur during the course of a chemical reaction.
Collision theory: This theory explains how chemical reactions take place, by assuming that the reacting molecules collide with each other.
Activation energy: The minimum amount of energy that is needed to initiate a chemical reaction.
Catalysts: A substance that increases the rate of a chemical reaction without being consumed or undergoing any permanent chemical change itself.
Enzymes: A biomolecule that catalyzes and speeds up chemical reactions in living organisms.
Arrhenius equation: This equation describes the temperature dependence of reaction rates in chemical reactions.
Order of a reaction: The order of a reaction refers to the power to which the concentration of a reactant is raised in the rate law.
Half-life: The time taken for the concentration of a reactant to decrease to half of its initial value.
Reaction equilibrium: The state in which the rates of the forward and reverse reactions are equal.
Le Chatelier's principle: This principle helps to predict how the equilibrium of a reaction will shift in response to changes in concentration, temperature, and pressure.
Reaction kinetics in the gas phase: The study of the kinetics of chemical reactions that occur in the gas phase.
Reaction kinetics in the liquid phase: The study of the kinetics of chemical reactions that occur in the liquid phase.
Reaction kinetics in the solid state: The study of the kinetics of chemical reactions that occur in the solid state.
Reaction rate: Reaction rate is the measurement of the speed at which a chemical reaction occurs. It is usually expressed as the change in concentration of reactants or products over time.
Collision theory: Collision theory explains how chemical reactions occur and why some reactions occur faster than others. According to this theory, molecules must collide in a certain way to react, and the greater the number of collisions, the faster the reaction rate.
Rate laws: Rate laws describe the mathematical relationship between the rate of a chemical reaction and the concentrations of the reactants.
Order of reaction: The order of reaction refers to the dependence of the reaction rate on the concentration of a reactant. The order of reaction can be zero, first, second, or higher depending on the number of molecules involved in the reaction.
Arrhenius equation: The Arrhenius equation describes the temperature dependence of the reaction rate. It shows that the rate of a reaction increases with temperature.
Activation energy: Activation energy is the minimum energy required for a chemical reaction to occur. The higher the activation energy, the slower the reaction rate.
Reaction mechanism: A reaction mechanism explains the steps involved in a chemical reaction, including the formation of intermediate species.
Catalysis: Catalysis is the process of increasing the rate of a chemical reaction by adding a substance called a catalyst. Catalysis lowers the activation energy and makes the reaction faster.
Enzyme kinetics: Enzyme kinetics studies the catalytic behavior of enzymes. Enzymes are biological catalysts that speed up chemical reactions in living organisms.
Surface chemistry: Surface chemistry studies the behavior of chemical reactions at the interface between two phases, such as a solid and a gas or a liquid and a gas.
Photochemistry: Photochemistry is the study of the interaction between light and matter in a chemical reaction. The energy of light can drive chemical reactions.
Electrochemistry: Electrochemistry is the study of the relationship between electrochemical reactions and electrical energy. Electrochemical reactions involve the transfer of electrons between two species.
