Gibbs-Helmholtz equation: It is a thermodynamic equation that determines change in gibbs free energy as an function of temperature and pressure for the system.

Gibbs-Helmholtz equation is used by taking temperature and pressure as an independent variable. It is necessary to take temperature and pressure as an independent variable because these variable can be easily control in system according to condition and other factor like volume, entropy can't be control according to reaction.

Correct form of Gibbs-Helmholtz equation is

$dG=-SdT+VdP$
