The equivalent conductance of NaCl at concentration C and at infinite dilution are $\lambda_C$ and $\lambda_{\infty}$, respectively. The correct relationship between $\lambda_C$ and $\lambda_{\infty}$ is given as: <br> (where the constant B is positive)

Question

( A ) $\lambda_C = \lambda_{\infty} - (B) \sqrt{C}$
( B ) $\lambda_C = \lambda_{\infty} + (B) {C}$
( C ) $\lambda_C = \lambda_{\infty} + (B) \sqrt{C}$
( D ) $\lambda_C = \lambda_{\infty} - (B) {C}$
