A) (III) (I) (II) (V)
B) (II) (v) (I) (IV)
C) (III) (IV) (I) (II)
D) (V) (I) (IV) (II)
Correct Answer: C
Solution :
Potential of hydrogen electrode at pH =10 is \[-0.\text{591V}\]. Reduction potential of \[C{{u}^{2+}}/Cu\]is \[0.36V\] Oxidation potential of\[Zn/Z{{n}^{2+}}\]is \[0.76V\] \[\frac{2.303RT}{F}=\frac{2.303\times 8.314\times 298}{96500}=0.059\]
