Question

If two liquids A and B form minimum boiling azeotrope at some specific composition then . (A) A-B interactions are stronger than those between A-A or B-B (B) vapour pressure of solution increases because more number of molecules of liquids A and B can escape from the solution (C) vapour pressure of solution decreases because less number of molecules of only one of the liquids escape from the solution (D) A-B interactions are weaker than those between A-A or B-B

The solutions which show a large positive deviation from Raoult’s law (i.e. A-B interactions are weaker than those between A-A or B-B) form minimum boiling azeotrope at a specific composition.

Q. 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 $B - B$

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 $B - B$

The solutions which show a large positive deviation from Raoult’s law (i.e. $A - B$ interactions are weaker than those between $A - A$ or $B - B$ ) form minimum boiling azeotrope at a specific composition.

Q. 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

vapour pressure of solution increases because more number of molecules of liquids A and B can escape from the solution
