a. Plot the appropriate polarization curves for the following half cell reactions and determine the corrosion potential and corrosion rate (current density) assuming activation control of both the anodic and cathodic processes. 10-8A/cm, M = M+ + e, e = -0.7 V, io = io 10-6A/cm, = Ba = +0.1 V 2H+ + 2e H, e = +0.1 V, (b) Same as (a), but assume the limiting current density for the reduction reaction is 105 A/cm. Again determine the corrosion potential and corrosion rate from your plot. = -0.1 V
