YOUR ANSWER : ?

At equilibrium condition, the chemical potential of a material in different phases in contact with each other is equal. The chemical potential for a real gas (μ) is given by(where, μ = standard chemical potential at unit fugacity (f° = 1 atm.) and the gas behaves ideally.)

μ° + T lnf

μ°+ R lnf

μ° + R/T lnf

μ° + RT ln f
