the Gibbs-Helmholtz equation

1. (thermodynamics) An equation for calculating changes in the Gibbs free energy of a system as a function of temperature: ${\displaystyle \left({\frac {\partial \left({\frac {G}{T}}\right)}{\partial T}}\right)_{p}=-{\frac {H}{T^{2}}},}$ where H is the enthalpy, T the absolute temperature and G the Gibbs free energy of the system, all at constant pressure p.
