Lead experiences corrosion in an acid solution according to the reaction

The rates of both oxidation and reduction half-reactions are controlled by activation polarization.

(a) Compute the rate of oxidation of Pb (in mol/cm2-s) given the following activation polarization data:

(b) Compute the value of the corrosionpotential.

For Lead P/P62+) =-0.126 V For Hydrogen '(H+ /H2) = OV i0

For Lead P/P62+) =-0.126 V For Hydrogen '(H+ /H2) = OV i0 = 2 x 10-9 A/cm? B= +0.12 i0 = 1.0 x 10-8 A/cm2 B=-0.10
