Lead experiences corrosion in an acid solution according to the following reaction, Pb + 2H+ rightarrow Pb2+ + H2 The rates of both oxidation and reduction half reactions are controlled by activation polarization as given below. Compute the rate of oxidation of Pb (in mol/cm -s). Compute the value of the corrosion potential. How long do you think corrosion would take to eat away a 0.1-mm thick surface layer of the lead sheet?
