A mixture of benzene and toluene is fed to a distillation column at a rate of 1000 kg/h. The feed composition is 40% benzene and 60% toluene by mass. The desired product streams are a distillate stream containing 80% benzene and 20% toluene, and a bottoms stream containing 20% benzene and 80% toluene. Determine the following: The molar flow rates of benzene and toluene in the feed stream. The molar flow rates of benzene and toluene in the distillate and bottoms streams. The overall mole fraction of benzene in the feed, distillate, and bottoms streams.
