We wish to flash distill a mixture that is 45 mole % benzene and 55 mole % toluene. feed rate to the still is 700 moles/hr. equilibrium data for the benzene-toluene system can be approximated with a constant relative volatility of 2.5, where benzene is more volatile. operation of the still is at 1 atm.

a) plot a y-x diagram for benzene.

b) if 60% of the feed is vaporized, find the liquid and vapor compositions.

c) if we desire a vapor composition of 60 mole %, what is the corresponding liquid composition, and what are the liquid and vapor flow rates?
