represents the distillation of mixture of liquid `A` and liquid `B` which gives both of pure liquid `A` and `B` . Represents the azeotropic mixture of `HNO_(3)` and `H_(2)O` which distillation gives an azeotropic mixture and either of pure liquid. We cannot separate both the pure liquid, i.e., `H_(2)O` and `HNO_(3)`.
At temperature `T_(1)` and composition `Q`, which of the following is true?

a.Vapour phase is richer in B while liquid phase is richer in A .
b.Distillation of composition Q gives only pure A .
c.Distillation of composition Q gives only pure A and pure B .
d.Distillation of composition Q gives higher percentage of B and A .

Options

A. Vapour phase is richer in `B` while liquid phase is richer in `A`.
B. Distillation of composition `Q` gives only pure `A`.
C. Distillation of composition `Q` gives only pure `A` and pure `B`.
D. Distillation of composition `Q` gives higher percentage of `B` and `A`.

Answer

A, C, D

Explanation

Composition `Q` lies closer to component `B`, and at temperature `T_(1)`, vapour phase will contain more of `B`.
