Question: Using vapor pressure data from Exercises 4.6 and 4.8 and the enthalpy data provided below: (a) Construct an h-x-y diagram for the benzene-toluene system at

Using vapor pressure data from Exercises 4.6 and 4.8 and the enthalpy data provided below:

(a) Construct an h-x-y diagram for the benzene-toluene system at 1 atm (101.3 kPa) based on the use of Raoult's and Dalton's laws.

(b) Calculate the energy required for 50 mol% vaporization of a 30 mol% liquid solution of benzene in toluene, initially at saturation temperature. If the vapor is then condensed, what is the heat load on the condenser in kJ/kg of solution if the condensate is saturated and if it is subcooled by10?C?
