(i) \[Zn\,(s)|Z{{n}^{2+}}(0.1\,M)||C{{u}^{2+}}(1M)|(Cu\,(s)\] |
(ii) \[Zn\,(s)|Z{{n}^{2+}}(1\,M)||C{{u}^{2+}}(1M)|(Cu\,(s)\] |
(iii) \[Zn\,(s)|Z{{n}^{2+}}(1\,M)||C{{u}^{2+}}(0.1\,M)|(Cu\,(s)\] |
A) \[{{E}_{2}}>{{E}_{1}}>{{E}_{3}}\]
B) \[{{E}_{1}}>{{E}_{2}}>{{E}_{3}}\]
C) \[{{E}_{3}}>{{E}_{1}}>{{E}_{2}}\]
D) \[{{E}_{3}}>{{E}_{2}}>{{E}_{1}}\]
Correct Answer: B
Solution :
\[E={{E}^{o}}+\frac{0.059}{2}\log \frac{[C{{u}^{2+}}]}{[Z{{n}^{2+}}]}\] \[\therefore \] \[{{E}_{1}}>{{E}_{2}}>{{E}_{3}}\]You need to login to perform this action.
