Chemical kinetics, also known as reaction kinetics, is the study of how fast chemical reactions occur and the factors that affect these rates. It's a branch of physical chemistry that's different from chemical thermodynamics, which deals with the direction in which a reaction occurs.  Chemical kinetics studies the rate of chemical reactions, which is the rate at which reactants are transformed into products. The rate of a chemical reaction is proportional to the concentrations of the reactants, and the mathematical expression of this relationship is known as the rate law.  Some applications... Show more
