Question

Why the molar conductance of increases with increase on dilution?

Answer 1

With increase in dilution, molar conductivity increases,

$\wedge =K\times \frac{1}{C}$

$K$ decreases as the number of ions per unit volume carrying the current decreases on dilution.

Concentration decreases, $\frac{1}{C}$ increases which overcomes, decreases in conductivity. Hence molar conductivity increases.
