40 kmol of mixture containing 45% acetaldehyde (A) and 55% ethanol (B) in moles will be separated by differential (simple discontinuous) distillation at 1.013 bar. The distillation process will be terminated when the mole fraction of acetaldehyde in the boiler reaches 0.15. In Figure 1, the boiling point diagram of the acetaldehyde-ethanol system at 1.013 bar is given. a)Find the vessel temperature at the end of the distillation b)the average concentration of the upper product c) the% recovery of acetelaldehyde
