Question
Select correct statement ?
Options
A.Heats of vaporisation for a pure solvent and for a solution are similar because similar intermolecular forces between solvent molecules must be overcome in both cases
B.Entropy change between solution and vapour is smaller than the entropy change between pure solvent and vapour
C.Boiling point of the solution is larger than that of the pure solvent
D.All are correct statements
Solution
All are facts.
We should remember that, Entropy of solution is more than entropy of pure solvent. So the difference in entropy change will be less in case of solution.
