The reduction potential of an electrode can be increased by

Options

  1. Aincreasing the area of the electrode
  2. Bdecreasing the temperature
  3. Cincreasing the temperature
  4. Ddecreasing the concentration of metal ions

Correct answer

B. decreasing the temperature

Step-by-step solution

The reduction potential of an electrode can be increased by increase in [M^ n+ ] or decrease in temperature. M^ n+ +n e⁻ M (Reduction) E=E^ - R T n F [M] [M^ n+ ]
