Answer & Solution
Correct Answer
(A) \(2.5 \times 10^{-3}\)
Step-by-step Solution
Detailed explanation
The nernst equation for reduction potential of an electrode is ;- \(\mathrm{E}=\mathrm{E}^{\circ}-\frac{2.303 \mathrm{RT}}{\mathrm{nF}} \log \frac{\left[\mathrm{Cl}^{-}\right]}{\mathrm{P}_{\mathrm{Cl}_2}}\) or,…
