In a narrow range of composition changes, the vapor-liquid equilibrium mixture of A and B is expressed by y = 1.15 x + 0.1593, where x and y are mole fractions of A in the liquid and vapor phase, respectively. Accordingly, the vapor-liquid equilibrium temperatures may be expressed as T(°C) = -32.68 x +108.43. A mixture of A and B is distilled in a batch (differential) system. Initially, 100 moles liquid mixture containing 30 mol% A- 70 mol% B are charged to the pot. The distillation is stopped when 10 mol% of the liquid has evaporated. Determine: 1- Final composition of the liquid in the pot, molA / mol 2- Average concentration of the distillate, mol A/mol 2- The start and end point temperatures of the pot, °C.
