Q. No.Consider the given two statements:
| Assertion(A): | \(\mathrm{E^0_{cell}}\) = 0 for a chloride ion concentration cell. |
| Reason(R): | For this concentration cell, the equation is given by: \(E_{\mathrm{cell}}=\frac{R T}{n F} \ln \left(\frac{\left[\mathrm{Cl}^{-}\right]_{\mathrm{LHS}}}{\left[\mathrm{Cl}^{-}\right]_{\mathrm{RHS}}}\right) \) |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A) |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
