van't Hoff equation

[van′tȯf i‚kwā·zhən]
(physical chemistry)
An equation for the variation with temperature T of the equilibrium constant K of a gaseous reaction in terms of the heat of reaction at constant pressure, Δ H: d (ln K)/ dT = Δ H/RT 2, where R is the gas constant. Also known as van't Hoff isochore.

The Gibb's free energy IGo is related to the enthalpy change (IHo) and entropy change (ISo) at a constant temperature by the Van't Hoff equation as shown below:
The effect of temperature on BSA-ligands binding is summarized in van't Hoff equation.
The enthalpy change ([DELTA][H.sup.0]) was regarded as a constant when the temperature changed little, then enthalpy change ([DELTA][H.sup.0]) and entropy change ([DELTA][S.sup.0]) can be obtained from Van't Hoff equation [15]:
