The feed to a distillation column is a 60 mol% benzene, 40 mol% toluene liquid. The vapor stream leaving the top of the column, which contains 95.0 mol% benzene and the balance toluene, goes to a total condenser. Half of the liquid condensate is returned to the top of the column as reflux and the rest is withdrawn as overhead product at a rate of 75 mol/h. The distillate (overhead product) contains 90% of the benzene fed to the column. The liquid stream leaving the bottom of the column goes to a reboiler. The exiting vapor stream is returned to the column as a boilup and the residual liquid is withdrawn as a bottoms product. Determine compositions and flow rates for each stream. All processes are at 1 atm. pressure
