A mixture containing 60 mol% benzene and 40 mol% toluene is subjected to differential distillation at 1 atm, under three different conditions:1. Until the distillate contains 70 mol% benzene2. Until 40 mol% of the feed is evaporated3. Until 60 mol% of the original benzene leaves in the vaporUsing α= 2.43, determine for each of the three cases: (a) number of moles in the distillate for 100 mol of feed; (b) compositions of distillate and residue.
