Phase diagramRelated: Equality of chemical potentials helps define coexistence between phases.
VolatilityRelated: Phase equilibrium occurs when chemical potentials match across coexisting phases.
Partition coefficientRelated: At equilibrium, a solute’s chemical potential is equal across phases.
FugacityRelated: Its dependence on fugacity gives the quantity its role in equilibrium calculations.
MetasomatismRelated: Chemical-potential differences drive elements between fluid and rock.
