The vapor pressures of pure liquids A and B are 53.2 and 40.3 kPa respectively, at 35o C. The total vapor pressure for a mixture with liquid mole fraction XA = 0.60 is 52.7 kPa. The vapor phase mole fraction is YA = O. 725. The excess molar enthalpy is +260 J mol-1.

calculate:

(i) The partial vapor pressures of A and B over the mixture.

(ii) The activities and activity coefficients of A and B.

(iii) The excess chemical potentials of A and B.

(iv) The excess Gibbs energy of the mixture
