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) |

3. | (A) is True but (R) is False. |
4. | (A) is False but (R) is True. |
For the following cell with hydrogen electrodes at two different pressures p1 and p2
Pt(H2) | H+(aq) |Pt (H2)
p1 1M p2
emf is given by:
1. \(\frac{R T}{F} \log _{e} \frac{P_{1}}{p_{2}}\)
2. \(\frac{R T}{2F} \log _{e} \frac{P_{1}}{p_{2}}\)
3. \(\frac{R T}{F} \log _{e} \frac{P_{2}}{p_{1}}\)
4. \(\frac{R T}{2F} \log _{e} \frac{P_{2}}{p_{1}}\)
The reduction potential of hydrogen half-cell will be negative if:
