Keq definition chemistry
WebThe binding constant, or affinity constant/association constant, is a special case of the equilibrium constant K, and is the inverse of the dissociation constant.It is associated with the binding and unbinding reaction of receptor (R) and ligand (L) molecules, which is formalized as: R + L ⇌ RL. The reaction is characterized by the on-rate constant k on … Webweb equilibrium constants are used to define the ratio of concentrations at equilibrium for a reaction at a certain temperature in general we use the symbol k k k k or k c k text c k c k start subscript start text c end text end subscript to represent equilibrium constants general chemistry ii lab 7 determination of the - Sep 25 2024
