  1. Equilibrium constant

    The equilibrium constant of a chemical reaction is the value of its reaction quotient at chemical equilibrium, a state approached by a dynamic chemical system after sufficient time has elapsed at which its composition has no measurable tendency towards further change. For a given set of reaction conditions, the equilibrium constant is independent of the initial analytical concentrations of the reactant and product species in the mixture. Thus, given the initial composition of a system, known equilibrium constant values can be used to determine the composition of the system at equilibrium. However, reaction parameters like temperature, solvent, and ionic strength may all influence the value of the equilibrium constant. A knowledge of equilibrium constants is essential for the understanding of many chemical systems, as well as biochemical processes such as oxygen transport by hemoglobin in blood and acid–base homeostasis in the human body. Stability constants, formation constants, binding constants, association constants and dissociation constants are all types of equilibrium constants.

  1. equilibrium constant

    The equilibrium constant, often denoted as K, is a measure of the ratio of the concentrations of products to reactants at equilibrium in a chemical reaction at a given temperature. It describes the balance between the forward and reverse reactions, providing an indication of which direction the reaction favors. If K is large (greater than 1), the reaction favors the product side. If K is small (less than 1), it favors the reactants. These concentrations are each raised to the power of their stoichiometric coefficients in the balanced chemical equation. The equilibrium constant helps to predict the extent of a reaction, whether it is almost complete, partial, or nearly zero.

  1. Equilibrium constant

    For a general chemical equilibrium the thermodynamic equilibrium constant can be defined such that, at equilibrium, where curly brackets denote the thermodynamic activities of the chemical species. This expression can be derived by considering the Gibbs free energy change for the reaction. If deviations from ideal behaviour are neglected, the activities may be replaced by concentrations, [A], and a concentration quotient, Kc. Kc is defined which is equal to the thermodynamic equilibrium constant divided by a quotient of activity coefficients. For ideal behaviour this quotient has a value of 1, and Kc = K. A knowledge of equilibrium constants is essential for the understanding of many chemical systems, as well as biochemical processes such as oxygen transport by hemoglobin in blood and acid-base homeostasis in the human body. Stability constants, formation constants, binding constants, association constants and dissociation constants are all types of equilibrium constant.
