Question
For the cell: Ni|Ni2+||Cu2+|Cu; E° = 0.77 V. By which of the following activity, Ecell will increase?
Options
A.On decreasing [Ni+2]
B.On decreasing [Cu+2]
C.On increasing mass of Ni electrode
D.On increasing mass of Cu electrode
Solution
$E_{cell} = E_{cell}^{o} - \frac{RT}{2F}.\ln\frac{\left\lbrack Ni^{2 +} \right\rbrack}{\left\lbrack Cu^{2 +} \right\rbrack}$
