Assertion:Molar conductivity increases with decrease in concentration.
Reason:Conductivity always decrease with decrease in concentration.

A

If both assertion and reason are true and reason is the correct explanation of assertion .

B

If both assertion and reason are true but reason is not the correct explanation of assertion .

C

If assertion is true but reason is false .

D

If both assertion and reason are false .

Text Solution

Verified by Experts

The correct Answer is:
B
`lambda_m=KV`
With decrease in concentration , total volume V of the solution containing one mole of electrolyte also increases and decreases in K (conductivity) on dilution of a solution is more than compensated by increase in its volume, hence molar conductivity `(lambda_m)` increases.
