|---|---|---|---|---|---|
| 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 (Kc) or partial pressures (Kp) | ||||
| 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 (Qc) or pressures (Qp) | ||||
| reversible reaction | chemical reaction that can proceed in both the forward and reverse directions under given conditions |
