A rectification column is fed 100 kmol/h of a mixture of 50 mol% benzene and 50 mol% toluene at 101.32 kPa abs pressure. The feed is saturated vapor at dew point. The distillate is to contain 90 mol % benzene and the bottoms 10 mol% benzene. Given the information and using the McCabe-Thiele method, determine the following: (a) Molar flow rates (kmol/h) of distillate, and bottoms (b) Minimum reflux ratio (c) Minimum number of theoretical plates at total reflux
