Q3 (20 points) The following temperature/composition data were obtained for a mixture of two liquids A and B at 1 atm, where x is the mole fraction in the liquid and y is the mole fraction in the vapour at equilibrium. T(C) 120 110 0.73 0.96 140 0.10 XA YA 0.43 130 0.25 0.60 0.78 0.36 The boiling points are 105C for A and 150C for B. What is the composition of the vapour in equilibrium with the liquid of composition (a) XA = 0.35 and (b) X8 = 0.25
