Question

A simple batch still separating a feed that is 60.0 mol% 1,2 dichloroethane and 40.0 mol% 1,1,2-trichloroethane. Pressure is 1 atm. The relative volatility is constant, α_di-tri = 2.4.

The charge (F) is 1.3 kmol. The final still pot concentration is 30.0 mol% 1,2 dichloroethane. Find the final moles in still pot and the average mole fraction of distillate product.
Repeat part a if F = 3.5 kmol.
If F = 2.0 kmol and the average distillate concentration is 75.0 mol% 1,2-dicholoroethane, find final kmoles in the still pot and the final mole fraction of 1,2 dichloroethane in the still pot.
