Correct Answer: C
Solution :
Potential of hydrogen electrode at \[pH=10\] is - 0.591V. Reduction potential of \[C{{u}^{2+}}/Cu\] is 0.36 V. Oxidation potential of \[Zn/Z{{n}^{2+}}\] is 0.76 V. \[\frac{2.303\,RT}{F}=\frac{2.303\times 8.314\times 298}{96500}=0.059\]You need to login to perform this action.
