Chemical equilibrium is the reaction state when the concentrations of reactants and products remain constant over time. The reaction does not stop, but it reaches a dynamic equilibrium when the rates of the forward and reverse reactions become equal. A mixture of reactants and products in the equilibrium state is called an equilibrium mixture. Let's consider a general reversible reaction where AA and BB are the reactants and CC and DD are the products: aA+bB⇌cC+dD�A+�B⇌�C+�D The concentrations in an equilibrium mixture are related by the equilibrium equation Kc=[C]c[D]d[A]a[B]b�c=[C]c[D]d[A]a[B]b where Kc�c is the equilibrium constant.
