(a) Demonstrate that the CPR is related to the corrosion current density i (A/cm2) through the expression

where K is a constant, A is the atomic weight of the metal experiencing corrosion, n is the number of electrons associated with the ionization of each metal atom, and ? is the density of the metal.

(b) Calculate the value of the constant K for the CPR in mpy and i in ?A/cm2 (10???6 A/cm2).
