If the ratio of the concentrations of the oxidized and reduced forms of a species in an electrochemical reaction can be given as [Ox]/[Red]=1.0×10−3[\mathrm{Ox}] /[\mathrm{Red}]=1.0 \times 10^{-3}, the correct expression among the following at 25∘C25^{{}^{{}^{\circ}}} \mathrm{C} is

Options

  1. AE=Eo+13(0.0592/n)\mathrm{E}=\mathrm{E}^{\mathrm{o}}+\frac{1}{3}(0.0592 / \mathrm{n})
  2. BE−Eo=3×(0.0592/n)E-E^o=3 \times(0.0592 / n)
  3. CE=E∘−13(0.0592/n)\mathrm{E}=\mathrm{E}^{{}^{{}^{\circ}}}-\frac{1}{3}(0.0592 / \mathrm{n})
  4. DE−E0=(0.0592/n)1/3E-E^0=(0.0592 / n)^{1 / 3}

Correct answer

B. E−Eo=3×(0.0592/n)E-E^o=3 \times(0.0592 / n)
