chemical equilibrium
51equilibrium constant — a constant, K (or Keq), describing the amounts of reactants and products of a chemical reaction at equilibrium at constant temperature; technically defined by thermodynamic activities, it is usually approximated using concentrations (and… …
52equilibrium constant — /ikwəˈlɪbriəm kɒnstənt/ (say eekwuh libreeuhm konstuhnt) noun a ratio which, for a reversible chemical reaction at equilibrium, expresses the concentrations of those chemicals formed in the forward reaction divided by the concentrations of those… …

54Dynamic equilibrium — For the economic concept, see Dynamic equilibrium (economics) A dynamic equilibrium exists once a reversible reaction ceases to change its ratio of reactants/products, but substances move between the chemicals at an equal rate, meaning there is… …

56Solubility equilibrium — is any type chemical equilibrium between solid and dissolved states of a compound at saturation. Solubility equilibria involve application of chemical principles and constants to predict solubility of substances under specific conditions (because …
57Thermodynamic equilibrium — In thermodynamics, a thermodynamic system is said to be in thermodynamic equilibrium when it is in thermal equilibrium, mechanical equilibrium, and chemical equilibrium. The local state of a system at thermodynamic equilibrium is determined by… …
58Schlenk equilibrium — The Schlenk equilibrium is a chemical equilibrium named after its discoverer Wilhelm Schlenk taking place in solutions of Grignard reagents. [W. Schlenk, W. Schlenk, Chem. Ber. 62, 920 1929 Note: the authors are father and son ] [ Grignard… …
59Partition equilibrium — The most common chemical equilibrium systems involve reactants and products in the same phase either all gases or all solutions. However, it is also possible to get equilibria between substances in different phases, such as two liquids that do… …
60acid-base equilibrium — noun (physiology) the normal equilibrium between acids and alkalis in the body with a normal acid base balance in the body the blood is slightly alkaline • Syn: ↑acid base balance • Topics: ↑physiology • Hypernyms: ↑ …
