# The equivalent conductance of

Question:

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

1. $\lambda_{\mathrm{C}}=\lambda_{\infty}-(\mathrm{B}) \sqrt{\mathrm{C}}$

2. $\lambda_{\mathrm{C}}=\lambda_{\infty}+(\mathrm{B}) \sqrt{\mathrm{C}}$

3. $\lambda_{\mathrm{C}}=\lambda_{\infty}+(\mathrm{B}) \mathrm{C}$

4. $\lambda_{\mathrm{C}}=\lambda_{\infty}-(\mathrm{B}) \mathrm{C}$

Correct Option: 1

Solution:
