Chemical kinetics is the study of the rates of chemical reactions. It involves the measurement of the rate of reaction, the determination of the rate law, and the study of the factors that affect the rate of reaction. The rate of reaction is typically expressed as the change in concentration of a reactant or product per unit time.
rate = k[A]^m[B]^n
The rate law is a mathematical expression that describes the relationship between the rate of reaction and the concentrations of the reactants. It is usually expressed in the form: chemical kinetics and dynamics steinfeld pdf
