For weak electrolyte, sudden increase in molar conductance with dilution. Prove this statement.

Explanation

For a weak electrolyte, at high concentration the plot is almost parallel to concentration axis with slight increase in conductivity as the dilution increases.
When the concentration approaches zero, there is a sudden increase in the molar conductance and the curve is a almost parallel to `Lambda_m` axis.
This is due to the fact that the dissociation of the weak electrolyte increases with the increase in dilution (Ostwald.s dilution law).
