The Volmer surface equation of state, belongs to the family of van der Waals equations; the deviation from ideality resides in a single parameter interpreted as second two-dimensional virial coefficient. Coupled whit the Gibbs adsorption equation, it generates the corresponding surface equation as a function of the bulk composition under dilution or saturation condition.

Keywords : Volmer isotherm; surface tension; surface equation of state; second virial coefficient; surface chemical potential.
