QI: A batch fractionation is carried out in small column which has the separation power of six theoretical plates, the mixture consist of A and B with 0.6 mol% of A, a distillation is required at constant composition of 98mol% and the operation is discontinued when 83% of A charged has been removed as distilled. Estimate the reflux ratio needed at started and at the final of distillation if relative volatility of A to B is 2.46
