If two liquids A and B from minimum boiling azeotrope at some specific composition then ……

Answer»

A - B interactions are stronger than those between A-A or B-B.
Vapour PRESURE of solution increases because more number of molecules of liquids A and B can escape from the solution.
Vapour pressure of solution decreases because less number of molecules of only one of the liquids escape from the solution.
A-B interactions are weaker than those between A-A or B-B.

Solution :Explanation : (i) The solutions which show LARGE positive deviation from Rault.s law form minimum BOILING azeptrope at some specific composition.
(ii) In case of positive deviation from Rault.s law A-B interactions are weaker than those between A-A or B-B.
