The reduction potential of an electrode can be increased by
- A increasing the area of the electrode
- B decreasing the temperature
- C increasing the temperature
- D decreasing the concentration of metal ions
Answer & Solution
Correct Answer
(B) decreasing the temperature
Step-by-step Solution
Detailed explanation
The reduction potential of an electrode can be increased by increase in \(\left[M^{n+}\right]\) or decrease in temperature. \(M^{n+}+n e^{-} \longrightarrow M\) (Reduction) \(E=E^{\circ}-\frac{R T}{n F} \ln \frac{[M]}{\left[M^{n+}\right]}\)
