Chemical potential (an intensive property) of a substance is a force that drives the chemical system to equilibrium and is equal to its partial molar properties. The ratio of chemical potential to free energy of a pure substance at constant temperature and pressure is________________?

Question

Accepted Answer

1. The chemical potential ($\mu$) of a substance is defined as the change in Gibbs free energy ($G$) when one mole of that substance is added at constant temperature and pressure. Thus, $\mu = (\partial G / \partial n)_{T, P}$, meaning the ratio $\mu/G$ is not generally 1.
