What is the electrode potential E(Mn+/ M) when the concentration of solid M is taken as unity?

Options

  1. AEo(Mn+/ M)) - RT/nF ln [M] / [Mn+]
  2. BEo((Mn+/ M)) - RT/nF ln 1 / [Mn+]
  3. CEo(Mn+ / M) - RT/nF ln [Mn+]
  4. DEo(Mn+/ M) - RT/nF ln 1 / [M]

Correct answer

B. Eo((Mn+/ M)) - RT/nF ln 1 / [Mn+]

Step-by-step solution

When the concentration of solid M is taken as unity, the electrode potential E(Mn+ / M) is given by Eo((Mn+/ M)) - RT/nF ln 1 / [Mn+].
