A fractionating column is required to distill a liquid containing 25 percent benzene and 75 percent toluene by mass, to give a product of 90 percent benzene. A reflux ratio of 3.5 is to be used, and the feed will enter at its boiling point. If the plates used are 100 percent efficient, calculate by the Lewis–Sorel method the composition of liquid on the third plate and estimate the number of plates required using the McCabe–Thiele method.

A fractionating column is required to distill a liquid containing 25 percent benzene and
75 percent toluene by mass, to give a product of 90 percent benzene. A reflux ratio
of 3.5 is to be used, and the feed will enter at its boiling point. If the plates used are
100 percent efficient, calculate by the Lewis–Sorel method the composition of liquid
on the third plate and estimate the number of plates required using the McCabe–Thiele
method.
