Problem 1 Integrate physical properties with a Mass and Energy balance on a distillation column Consider the distillation separation problem in Assignment 4, problem 4. For the exact conditions that you solved in the mass balance, we will solve the energy balance. The Flow diagram, stream table and T-x-y diagram are shown below. (To refresh your memory, you can find both the question, and the solution on e-class.

Assume Raoult's law applies.Provide a suitable reference state for benzene, toluene [Hint, what is the lowest temperature you are likely to see?} and water, used in the condenser and reooiler but which does not contact the process. [Hint use the reference state for 1your source, often liquid water at the triple point]
