The influence of increasing solution velocity on the overvoltage-versus log-current density behavior for a solution that experiences combined activation–concentration polarization is indicated in Figure 17.27. On the basis of this behavior, make a schematic plot of corrosion rate versus solution velocity for the oxidation of a metal; assume that the oxidation reaction is controlled by activation polarization.
