Abstract
This chapter reviews the principles of chemical equilibrium beginning with the concept that many chemical reactions are reversible. These reversible reactions achieve a dynamic equilibrium where the rate of the forward reaction equals the rate of the reverse reaction. This dynamic equilibrium is described by an equilibrium constant, which is determined from the concentrations of the reactants and products at equilibrium. The magnitude of the equilibrium constant is presented as measure of the extent that the forward and reverse reactions take place. Le Chatelier's principle is introduced and the changes in reaction conditions that can disturb a chemical equilibrium are reviewed. The response of the chemical reaction to these changes in reaction conditions is explained in detail. The reaction quotient is presented as a means of determining the direction the reaction is likely to proceed.
