Definition

A thermodynamic relation that quantifies how an equilibrium constant K of a given chemical reaction changes with temperature: in its differential form, (d ln K)/(dT) = ΔH°(T)/(R T^2), where ΔH°(T) is the reaction enthalpy (often approximated as constant) and R is the gas constant. The equation links temperature dependence of equilibrium to reaction enthalpy under specified standard states.
