Compounds 1 and 2 have the following vapor pressures, in bar, and mixtures of these compounds in the vapor phase are well described as ideal gases at pressures of up to 5 bar.


The liquid molar volumes of these compounds are V1=125 cm3/mol and V2=90 cm3/mol, and can be assumed constant over the range of temperatures and pressures considered in this problem.

A) Mixtures of 1 and 2 at 80 ?C are well described by the two-parameter Margules equation, with A12 = -0.3 and A21 = -0.8. Compute the pressure and composition of a vapor phase that is in equilibrium with a liquid that contains 40 mol% compound 1 and 60 mol% compound 2 at 80 ?C.
B) The Wilson parameters for this system are ?12=0.7 and ?21=1.5 at 20 ?C. What are ?12 and ?21 at 60 ?C?
C) Using the Wilson parameters given in part B, determine the “infinite dilution” activity coefficients for compounds 1 and 2 at 20 ?C.
