Assertion: Molar conductivity of a weak electrolyte at infinite dilution cannot be determined experimentally. Reason: Kohlrausch law helps to find molar conductivity of a weak electrolyte at infinite dilution.

Answer»

If both assertion and reason are TRUE, and reason is the true explanation of the assertion
if both assertion and reason are true, but reason is not the true explanation of the assertion.
if assertion is true, but reason is false.
