Iron corrodes in acid solution to form Iron(II). Exchange current density for the anodic oxidation is 0.01Am2, the symmetry coefficient is 0.5 and the standard electrode potential is 0.44V. Given R=8.314JK1mol1,T=298K and F=96500Cmol1. (a) Determine the overpotential for anodic reaction of the iron at current density of 0.5Am2 (3 marks) (b) Calculate the corrosion potential at the same current density
