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

Text Solution

Verified by Experts

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.

Answer the question (given below) which are based on the following diagra. Consider some facts about the above phase diagram : Vapour pressure diagram for real solutions of two liquids A and B that exhibit a positive deviation from Raoult's law. The vapour pressure of both A and B are greater than predicted by Raoult's law. The dashed lines lines represented the plots for ideal solutions. Total vapour pressure of mixture of 1 mol of volatile component A(P_(A)^(@)=100 mmHg) and 3 mol of volatile component B(P_(B)^(@)=60 mmHg) is 75 mm . For such case:
