If the ratio of the concentrations of the oxidized and reduced forms of a species in an electrochemical reaction can be given as

[\mathrm{Ox}] /[\mathrm{Red}]=1.0 \times 10^{-3}

, the correct expression among the following at

25^{{}^{{}^{\circ}}} \mathrm{C}

is

Options

A $\mathrm{E}=\mathrm{E}^{\mathrm{o}}+\frac{1}{3}(0.0592 / \mathrm{n})$
B $E-E^o=3 \times(0.0592 / n)$
C $\mathrm{E}=\mathrm{E}^{{}^{{}^{\circ}}}-\frac{1}{3}(0.0592 / \mathrm{n})$
D $E-E^0=(0.0592 / n)^{1 / 3}$

Correct answer

B. $E-E^o=3 \times(0.0592 / n)$
