a )Sketch the temperature composition diagram for a binary mixture of two volatile liquids A (bp 75 C) and B (bp 90 C), which form an azeotrope (composition: 70% B, 30% A) that boils at 58 C.With the aid of the diagram draw in in in a) above predict what the approximate composition of the first drop of distillate would be in the distillation of a mixture containing 50% of each compound.
