From the results below for 10-2 M Mn(III) and 10-2 M Mn(IV):
1) estimate j0 and k0
2) What is the predicted exchange current density j0 for a solution with 1M Mn(III) and 1M Mn(IV) inside? Explain the difference between the Tafel plot shown and an ideal Tafel plot at large overpotential (e.g. 1.0 - 0.6 V vs NHE). Hint: find out where is the equilibrium potential of Mn3+/4+ from the plot first. Note that the left bottom corner is neither the original point nor the equilibrium potential.
