An equimolar mixture of benzene and toluene is subjected to a simple batch distillation at atmospheric pressure. For the purpose of this problem C3 = 2.55. If the distillation is discontinued when the moles of distillate amount to 60% of the moles charge, 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 percentage of the amount of benzene in the charge that goes to the distillate.

Question
An equimolar mixture of benzene and toluene is subjected to a simple batch distillation at atmospheric pressure.
For the purpose of this problem Ca3 = 2.55. If the distillation is discontinued when the moles of distillate
amount to 60% of the moles charge, 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 percentage of the amount of benzene in the charge that goes to the distillate.
