Answer & Solution

Correct Answer

(B) \(5\)

Step-by-step Solution

Detailed explanation

Anode \(: H _{2} \rightarrow 2 H ^{+}+2 e ^{-}\) Cathode: \(Cu ^{2+}+2 e ^{-} \rightarrow Cu\) \(\overline{ Cu ^{2+}+ H _{2} \rightarrow 2 H ^{+}+ Cu }\) \(E _{\text {cell }}= E _{\text {cell }}^{0}-\frac{0.06}{2} \log \frac{\left[ H ^{+}\right]^{2}}{\left[ Cu ^{2+}\right]}\)…
