Which of the following is not a correct relationship between $\lambda_c$ and $\lambda_\infty$ for $NaCl$? Here,$\lambda_c$ and $\lambda_\infty$ are the equivalent conductance at concentration $C$ and at infinite dilution,respectively.

  • A
    $\lambda_\infty = \lambda_c + b\sqrt{C}$
  • B
    $\sqrt{C} \lambda_\infty = \sqrt{C} \lambda_c + bC$
  • C
    $\lambda_\infty = \lambda_c - b\sqrt{C}$
  • D
    $\lambda_c = \lambda_\infty - b\sqrt{C}$
