Assertion: According to Kahlrausch law, the molar conductivity fo a strong electrolyte at infinite dilution is sum of molar conductivities of its ions.

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.
If both assertion and reason are false.

Solution :Correct A. The molar conductivity of any ELECTROLYTE (weak or strong) at infinite dilution is sum of molar conductivities of the ions multiplied by the respective number of ions in one formula unit.
Correct R. the CURRENT carried by CATIONS and anions is not equal.
