A gamma-phi formulation of vapour liquid equilibrium uses

  • A.an activity coefficient for liquid and a fugacity one for vapour
  • B.fugacity coefficients for both of the phases present
  • C.activity coefficients for both of the phases present
  • D.neither of these, working with the chemical potentials directly

Answer: A

It treats each phase with the model that suits it, which is why it handles strongly non-ideal liquids well. The alternative phi-phi approach uses one equation of state for both phases and suits high pressure hydrocarbon systems.
