The diagram given below is a vapour-pressure-composition diagram for a binary solution of `A` and `B`.

In the solution,`A-B` interactions are:
a. Similar to `A-A` and `B-B` interactions
b. Greater than `A-A` and `B-B` interactions
c. Smaller than `A-A` and `B-B` interactions
d. Unpredictable

A

Similar to `A-A` and `B-B` interactions

B

Greater than `A-A` and `B-B` interactions

C

Smaller than `A-A` and `B-B` interactions

D

Unpredictable

Text Solution

Verified by Experts

The correct Answer is:
C
c. The solution is showing positive deviation from Raoult's law. Therefore interaction between `A-A` and `B-B` is smaller than `A-B` interaction.
