Chemistry Question on Solutions
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
Answer
A−B interactions are weaker than those between A−A or B−B
Explanation
Solution
The solutions which show a large positive deviation from Raoult?? law (i.e. A−B interactions are weaker than those between A−A or B−B) form minimum boiling azeotrope at a specific composition.
