प्रश्न
If two liquids A and B form minimum boiling azeotrope at some specific composition then ______.
विकल्प
A–B interactions are stronger than those between A–A or B–B.
vapour pressure 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.
उत्तर
If two liquids A and B form minimum boiling azeotrope at some specific composition then A–B interactions are stronger than those between A–A or B–B..
Explanation:
(i) The solutions which show large positive deviation from Rault's law form n=minimum boiling azeotrope 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.
