Surface chemical potentials
Surface chemica1 potentials are defined by
The quantities thus defined can be shown to be identical, and the conditions of equilibrium of component
in the system to be

has to be omitted from this equilibrium condition if component
is not present in the respective bulk phase.)
The surface chemical potentials are related to the Gibbs energy functions by the equations
