The reason is the charge transfer is typically a thermally activated process, so the reaction rate scales as 0. 12/4. 5. 6. where 7 is the activation "overpotential,” or extra voltage (energy per charge), required to sustain the current. At room temperature, only a small overpotential (7∼ 9:;/ = 26 mV) is required
