Do For Fe corroding in the aerated solution with the concentration of ferrous ions is equal to 1 . 6 2 1 0 - 2

Do For Fe corroding in the aerated solution with the concentration of ferrous ions is equal to 1.6210-2
M, the anodic dissolution shows the activation polarization. The cathodic polarization curves at
velocity 1(V1) and velocity 2(V2) are shown in the following polarization diagram (some hints are
included). We have the following data for this corrosion system.
For the anodic process: ba,Fe=0.1V,io,a=10-8Am2
(a) Determine the equilibrium potential of the above Fe electrode.
(b) Sketch the activation polarization curve for anodic reaction on the diagram, and label the curves
completely, including the reactions. (Use theoretical polarization curve, i.e., ignore the
deviation near the equilibrium potential.)
(c) Is V1>V2 or V1?
(d)Is corrosion controlled by activation or diffusion atV1?
(e)Is corrosion controlled by activation or diffusion atV2?
(f) What is the corrosion current density at velocity 2?
(g) What is the corrosion potential at velocity 2?
(h) What is the corrosion potential at velocity 2vs. SCE?
