If two liquids A and B form minimum boiling azeotrope at some specific composition, then …………. .

Answer»

`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`

Solution :Minimum boiling azeotrope is formed when ACTUAL vapour pressure in HIGHER then expected, i.e., solution shows `+ve` deviation from RAOULT's law which is so when A-B interactions are weakder than A-A or B-B interactions.
