A trayed tower is to be designed to continuously distil 8000 kg/h of a binary mixture of 60 mol% benzene and 40 mol% toluene. A liquid bottoms product of 95 mol% and 5 mol% is preheated so that it enters the column with molar percent vaporization equal to the distillate-to-feed ratio. Use the McCabe Thiele method to compute the following, assuming a uniform pressure of 1 atm throughout the column. The relation between the mole fraction of benzene in liquid
