The benzene-toluene mixture containing 0.4 benzene by weight fraction is continuously preheated under pressure. This preheating is continued until the enthalpy of the liquid mixture becomes 72.3 kcal/kg. The mixture is then passed through a pressure reducing valve and sent to a separator at 101.3 kPa pressure conditions. By making the appropriate assumptions and using the enthalpy-composition diagram,

a) Calculate the compositions of the vapor and liquid phases obtained, b) Calculate the evaporation percentage.
