The same liquid mixture containing 60 mol% of component 1 and 40 mol% of compone

The same liquid mixture containing 60 mol% of component 1 and 40 mol% of component2, at the bubble point, is subjected to a batch distillation, using a column with 6 real dishes already present in the refinery, under a constant RR of 2.5. Knowing that 40% of the mixture is distilled and that the column has 85% efficiency, find distillate and residue compositions, proving if this column is sufficient for the separation of components, justifying your answer in detail.
