At 85oC, the vapor pressure of pure o-xylene is 55 Torr and thevapor pressure of pure p-xylene is 85 Torr. When liquid o-xylene ismixed with liquid p-xylene, the solution formed is ideal at allcompositions.
(a) Calculate ∆G, ∆H, and ∆S of mixing when liquid o-xylene andliquid p-xylene are mixed at 85oC, given that the mole fraction ofp-xylene is 0.30 and the solution contains a total of 4.0 mol ofmaterial.
(b) What are the mole fractions of o-xylene and p-xylene in thevapor at equilibrium with this solution?
