I HAVE ASKED THIS QUESTION FOR SEVERAL TIMES PLEASE ANSWER IF YOU KNOW THE CORRECT SOLUTION ON THE PAPER. PLEASE SOLVE AND EXPLAIN CLEARLY.

40kmol mixture containing 45% acetaldehyde (A) and 55% ethanol (B) in moles will be separated by differential (simple batch) distillation at 1.013 bar. The distillation process will be terminated when the residual mixture in the boiler reaches 22kmol. In Fig. 1, the boiling point diagram of the acetaldehyde-ethanol system at 1.013 bar is given. a) Find the mole fraction of residual mixture in the boiler b) Determine the boiler temperature at the end of distillation b) Calculate the average concentration of the top product c) Find the percentage recovery of acetelaldehyde Figure 1.
