Nickel experiences corrosion in an acid solution according to the reaction Ni + 2H† Ni²+ + H2 (a) The rates of both oxidation and reduction half-reactions are controlled by activation polarization. Compute the rate of oxidation of Ni (in mol/cm2-s) given the following activation polarization data: For Nickel For Hydrogen VNINIP") = -0.25 V i, = 10¬8 A/cm? B = +0.12 V(H'H) = i, = 6 × 10-7 A/cm² B = -0.10 0 V

Question
Nickel experiences corrosion in an acid solution according to the reaction Ni + 2H† → Ni²+ + H, (a) The rates of both oxidation and reduction half-reactions are controlled by activation polarization. Compute the rate of oxidation of Ni (in mol/cm2-s) given the following activation polarization data: For Nickel For Hydrogen V(H/H,) = 0 V i, = 6 × 10-7 A/cm² B = -0.10 V(NINP") = -0.25 V io = 10¬8 A/cm² B = +0.12 (b) Compute the value of the corrosion potential.
