Which of the following is the correct representation of the Nernst equation for the reduction reaction $M^{n+} + ne^- \rightarrow M$?

• A
  $E_{M^{n+}/M} = E^o_{M^{n+}/M} + \frac{0.0591}{n} \log [M^{n+}]$
• B
  $E_{M^{n+}/M} = E^o_{M^{n+}/M} - \frac{0.0591}{n} \log \frac{1}{[M^{n+}]}$
• C
  $E_{M^{n+}/M} = E^o_{M^{n+}/M} + \frac{0.0591}{n} \log \frac{1}{[M^{n+}]}$
• D
  None of these
