← ScienceWhich outcome affects electrolytic cell reaction rates when ion depletion occurs?
A)Electrode passivation reduces surface area
B)Overpotential increases activation energy
C)Concentration polarization limits charge transfer✓
D)Ohmic resistance promotes ionic conduction
💡 Explanation
Concentration polarization increases diffusional limitations, which limit the rate of ion transport to the electrode. Therefore, the rate decreases, rather than an increase in reaction activation energy affecting individual reactions, or improved conductivity helping counteract shortages.
