{wiki=Gibbs–Duhem_equation}
The Gibbs–Duhem equation is a relationship in thermodynamics that describes the changes in the chemical potential of a system in relation to its temperature, pressure, and composition. It arises from the fundamental thermodynamic definition of the differential change in the Gibbs free energy \\( G \\).
