1.

Assertion : Molar conductance of an electrolyte increases upon dilution. Reason : Ions move faster in dilute solution.

Answer»

If both ASSERTION and reason are correct and reason is correct explanation for assertion.
If both assertion and reason are correct but reason is not correct explanation for assertion.
If assertion is correct but reason is INCORRECT.
If assertion and reason both are incorrect.

Solution :(b) Correct explanation.Molar conductance increases because with DILUTION in a weak ELECTROLYTE, dissociation increases while in a strong electrolyte, inter-ionic attractions decrease.
