The thermodynamic equilibrium constant is also dimensionless because activities are dimensionless numbers. At equilibrium, ΔrG = 0 This important thermodynamic relation enables us to predict the equilibrium constant of any reaction from tables of thermodynamic data, and hence to predict the equilibrium composition of reaction mixtures. o ln −= ΔrGKRT版权所有：华东理工大学物理化学教研室 13 4) The general case of a reaction 9.1 The Gibbs energy minimum An equilibrium constant K expressed in terms of activities is called a thermodynamic equilibrium constant.
