A simple distillation column separates a binary mixture of A and B. The relative
volatility of A with respect to B is 2. The steady-state composition of A in the vapour
leaving the 1st, 2nd and 3rd trays in the rectifying section are 94, 90 and 85 mol%,
respectively. For ideal trays and constant molal overflow, the reflux-to-distillate
ratio is ______
Correct : a
