a A rectification column is fed with 100 kg-mol/h of a mixture of 50 mol% benzene and 50 mol% toluene at 101.32 KPa absolute pressure. The feed is a liquid at its boiling point. The distillate must contain 90 mol% benzene and the remainder 10 mol% benzene. The reflux ratio is 4.52:1. Calculate the kg-mol/h of distillate, kg-mol/h of residue, the feed tray, the number of theoretical trays, and the number of actual trays needed to carry out this process if the efficiency is 80% and the value of "q" by means of the McCabe- Thiele method.
