equilibrium | state of a reversible reaction in which the forward and reverse processes occur at equal rates

equilibrium constant (K) | value of the reaction quotient for a system at equilibrium; may be expressed using concentrations (K_c) or partial pressures (K_p)

heterogeneous equilibria | equilibria in which reactants and products occupy two or more different phases

homogeneous equilibria | equilibria in which all reactants and products occupy the same phase

law of mass action | when a reversible reaction has attained equilibrium at a given temperature, the reaction quotient remains constant

Le Chatelier’s principle | an equilibrium subjected to stress will shift in a way to counter the stress and re-establish equilibrium

reaction quotient (Q) | mathematical function describing the relative amounts of reactants and products in a reaction mixture; may be expressed in terms of concentrations (Q_c) or pressures (Q_p)

reversible reaction | chemical reaction that can proceed in both the forward and reverse directions under given conditions
