2a. A distiiation colum treats a mixture of benzene and tolucne of 45% benzcile by weight and the mixlure is to be separated to glve a produck of 95% of benze: e at top and 10% by weight of benzene at the bollom. The feed enters the: colum at its boiling point at a reed rate of 5kg/s. The vapeut leaving the colunn is condensed but not cooled provktes reflux anul profict.
