Assertion : Potassium is not obtained by the electrolysis of fused KCl. Reason : Potassium vapourises at the melting point of KCl

Assertion : The boiling point of chloroform-acetone solution is larger than expected from ideal behaviour. Reason : The forces of attraction between unlike molecules are stronger than those between like molecules in the solution. This results in lower vapour pressure as compared to an ideal solution which is responsible for the higher boiling point.

Assertion : Higher the value of molal depression constant of solvent (K) used to prepare the solution, lower will be the freezing point of the solution. Reason : Depression in freezing point depends upon the nature of the solvent. a)If both (A) and (R) are correct and (R) is the correct explanation of(A). b)If both (A) and (R) are correct, but (R) is not the correct explanation of (A). c)If (A) is correct, but (R) is incorrect. d)If both (A) and (R) are incorrect.
