Chemical Equilibrium is achieved when the rates of the forward and reverse reactions are equal and the concentrations of the reactants and products remain constant.

Equilibrium constant (K)

A number equal to the ratio of the equilibrium conc. Of the products to the equilibrium concentrations of reactants, each raised to the power of its stoichiometric coefficient.

Law of mass action

For a reversible reaction at equilibrium and a constant temperature, a certain ratio of reactant and product concentrations has a constant value, K (equilibrium constant)

Acid Ionization Constant (K_a)

equilibrium constant for the acid ionization.

Base Ionization Constant (K_b)

Equilibrium constant for the base ionization

Ion-product Constant (K_w)

Product of the molar concentrations of H+ and OH- ions at a particular temperature.
