Two liquids `HNO_3` (A) and water (B) form a maximum boiling azeotrope when mixed in the ratio of 68% and 32% respectively . It means
Two liquids `HNO_3` (A) and water (B) form a maximum boiling azeotrope when mixed in the ratio of 68% and 32% respectively . It means
A. A-B interactions are stronger than A -A and B-B interactions
B. A-B interactions are weaker than A -A and B-B interactions
C. vapour pressure of solution is more than the pure components
D. vapour pressure of solution is less since only one component vaporises .

Correct Answer - A
Since the new interactions (A-B) are stronger than (A-A) and (B-B) interactions , the solution shows negative deviation, i.e. less vapour pressure and hence higher boiling point .
