Show Summary Details

Quick Reference

Symbol: μ. For a given component in a mixture, the coefficient ∂G/∂n, where G is the Gibbs free energy and n the amount of substance of the component. The chemical potential is the change in Gibbs free energy with respect to change in amount of the component, with pressure, temperature, and amounts of other components being constant. Components are in equilibrium if their chemical potentials are equal.
