WebThe excess energy associated with an interface is formally defined in terms of a surface energy.This may be expressed in terms either of Gibbs, G, or Helmholtz, A, free energies.In order to circumvent difficulties associated with the unavoidably arbitrary position of the surface plane, the surface energy is defined as the surface excess [7,8], i.e the excess … WebGibbs free energies of mixing for a hypothetical binary solution. A negative free energy of mixing (a) means that there is a thermodynamic driving force for mixing to occur (i.e. it will occur spontaneously), while a positive free energy of mixing (b) means that the pure components will not mix. www.msubbu.in
