Compounds G and H form non-ideal liquid solutions that can be described by the two-parameter Margules equation. The following is known:
• The vapor pressure of pure compound G at T=300 K is 1 bar. • The vapor pressure of pure compound H at T=300 K is 0.6 bar. • At T=300 K and P=0.8 bar, there is an azeotrope at which liquid and vapor are in equilibrium and both phases have a composition of 70% G and 30% H. A) Find the activity coefficients of compounds G and H in the azeotropic mixture described above. B) Find a general expression for the excess Gibbs energy of a liquid mixture of G and H at T=300 K. The only unknowns in your expression should be the mole fractions of G and H in the liquid phase.
