Question

In a solution showing, negative deviation.

(1) Boiling point increases, vapour pressure decreases.

(2) Boiling point decreases, vapour pressure increases.

(3) Both boiling point and vapour pressure decreases.

(4) Both boiling point and vapour pressure increases.

Answer 1

The correct option is (1) Boiling point increases, vapour pressure decreases.

For solution showing negative deviation VP decreases & BP increases. Because, interparticle attraction increases due to mixing.
