A binary mixture of benzene and toluene containing 40% of benzene is to be distilled at 1 atm pressure to recover 95% of the benzene. Estimate the molal percent of mixture to be distilled and the composition of the distillate obtained if distillation is carried out by Differential distillation, collecting all the distillate together.
The average relative volatility of benzene to toluene is 2.5.

In this problem, the mole percent of a mixure and distillate have been calculated by using Rayleigh Equation in Differential Distillation. The solution is detailed and well presented.
