Question

The EMF of the cell Ni `|Ni|Ni^(2+) ||Cu^(2+) |Cu(s)` is `0.59 ` volt. The standard reduction electrode potential fo copper electrode si `0.34` volt. The standard reduction electorde ptential of nickel electrode will be.
A. ` 0. 25 ` volt
B. ` -0. 25 k J`
C. ` 10 6 . 15 k J`
D. ` 53 . 07 k J`

Answer 1

Correct Answer - B
` -x = 0.59`
`x=0.3.4 - 0.59 =- 0.25 V`
