Which Is NOT True of Overpotential

Which is NOT true of overpotential?

A) Overpotential is the voltage required to overcome the activation energy for a reaction at an electrode.
B) The rate of the reaction will increase as the applied overpotential increases.
C) Activation energy,hence overpotential,is electrode-surface independent.
D) Applying an increasing overpotential will sustain a higher current density.
E) Current density is current per unit area of electrode surface,A/m².
