(physical chemistry)
A relation that imposes a condition on the composition variation of the set of chemical potentials of a system of two or more components, where S is entropy, T absolute temperature, P pressure, ni the number of moles of the i th component, and μi is the chemical potential of the i th component. Also known as Duhem's equation.
