3. A mixture of 0.30 mole fraction benzene and the rest toluene is fed to a continuous distillation column to give an overhead product of 0.90 mole fraction benzene and a bottom product of 0.95 mole fraction toluene. The feed enters at 283 ? with a specific heat capacity (??) of 1.84 ??/?? ? and a boiling point of 374.7 ?. The latent heat of vaporisation (λ) of the feed is 30 ??/????. If the reflux ratio is 5.0, a. How many theoretical plates are required? b. How many actual plates are required assuming a plate efficiency of 80 percent? (????????? = 78 ??/???? ; ????????? = 92 ??/????)
