For the reduction reaction, Mn+ + ne- arrow M E = E° - (RT/nF) In ([M]/[Mn+]) The value of E will increase if [Mn+] is increased or T is decreased

Q. The reduction potential of an electrode can be increased by

increasing the area of the electrode

decreasing the temperature

increasing the temperature

decreasing the concentration of metal ions.

For the reduction reaction,
$M^{n +} + n e^{-} \to M$
$E = E^{^{\circ}} - \frac{RT}{n F} I n \frac{[ M ]}{[ M ^{n +} ]}$
The value of E will increase if $[M^{n +}]$ is increased or T is decreased
