A binary mixture of water (1) and benzene (2) is in vapor-liquid equilibrium at a liquid mole fraction x1 5 0.6 and a pressure of 74.5 kPa. The liquid phase nonideality can be described by the two-suffix Margules equation with A/ 1 RT 2 5 2.74. Determine the temperature and the vapor phase mole fraction of a.
