A liquid mixture containing 30.0 mole% benzene(B),25%toluene(T),and the balance xylene(X) is fed to a distillatain column. the bottoms product contains 98.0mole%(X)and no (B),and 96.0% of the (X)in the feed is recovered in this stream. The over head product is fed to a second column. The overhead product from the second column contains 97,0% of the (B)in the feed to this column. The composition of this stream is 94.0%(B) and the balance (T)

a)Draw and lavel a flowchart of this process and do the degree-of-freedom analysis.

b)Calculate(i)the percentage of the benzene in the process feed(the feed to the first column) that emerges in the overhead product from the second column and (ii)the percentage of toluene in the process feed that emerges in the bottom product from the second column.
