Chemical reactions can be defined using many aspects including the type of reaction, the strength of the reaction and the rate of reaction. Often, the rate, or speed, of the particular reaction affects the properties of what occurs. For example, rate laws can be used to determine whether a reaction will occur spontaneously or not. More specifically, chemical kinetics refers to the rate at which a reaction occurs between the relative states of the reactants and products. At the same time, certain reactants and products produce different types of reactions. Acid-Base reactions, for instance, lead to the formation of salts and the nature of the exchange of ions in this case causes a fast reaction.

            There are many characteristics of a chemical reaction that can be determined using chemical kinetics and rate law derivations. These derivations usually involve the calculation of initial concentration and measured reaction rate. Once the overall reaction order is attained using the concentrations and rates, the rate equation can be determined to be used later for calculating instantaneous values. With the initial concentration, reaction rate and reaction order, the rate constant can be found.

            At the same time, chemical kinetics also involve concepts such as half-life, which is the amount of time for half of the initial concentration of the reactants to be reacted. In general, chemical kinetics is essential to the study of chemistry because it analyzes a reaction as a function of concentration and time, which allows us to better understand chemical reactions.
