Extracted text: An equimolar mixture of benzene and toluene is subjected to a simple batch distillation at atmospheric pressure. For the purpose of this problem CAB = 2.55. If the distillation is discontinued when 60% of the original benzene is in the distillate, calculate: a) The concentration in the distillate in % by mole benzene. b) The concentration of the residue in % by mole by mole benzene. c) The % of the moles of charge that goes to the distillate.
