Two liquids $$H{NO}_{3}(A)$$ and water $$(B)$$ form a maximum boiling azeotrope when mixed in the ratio of $$68$$% and $$32$$% respectively. It means :

AA-B interactions are stronger than A-A and B-B interactions
Correct Answer
BA-B interactions are weaker than A-A and B-B interactions
Cvapour pressure of solution is more than the pure components
Dvapour pressure of solution is less since only one component vaporises

Solution

Negative azeotropes are also called maximum boiling mixtures or pressure minimum azeotropes.
An example of a negative azeotropes is hydrochloric acid at a concentration of 20.2% and 79.8% water (by mass).
