A binary mixture with components A and B is to be separated in a distillation column to obtain 95 mol%. A as the top product. The binary mixture has a con stant relative volatility AB = 2. The column feed is a a - saturated liquid containing 50 mol % of A. Under the usual simplifying assumptions such as constant molal overflow, negligible heat loss, ideal trays, the mini mum reflux ratio for this separation is (rounded off to one decimal place)
2) Draw the isobaric phase diagram at 1 atm of the following two-component liquid system: water (Boiling point = 100°C) and nitric acid (Boiling point = 86°C), with the mass percentage of nitric acid on the x-axis.
