A Assume That The Entire Surface Has Been Active Assume That Anodic Area Cathodic Area Total Area The Solution Contains 1 (80.03 KiB) Viewed 37 times

a) Assume that the entire surface has been active assume that anodic area=cathodic area total area The solution contains 0.1 M HCL (pH =1), and a corrosion potential of Econ=-450 mV was measured, and where the chemical reactions are: 2H+ + 20 = H, Zn = Zn2+ + 2e Assume that both reactions are under activation polarization. Molar weight for zinc: M-65 Faradays number: F = 96500 coulomb AC current density for H*/H: io = 0.5 A/cm2 AC current density for Zn/Zna: in = 0.1 A/cm2 b) now assume that only the equilibrium potential for cathodic reaction is affection by a dilution of the solution to pH=5. what effect does this have on the corrosion rate? also enter this in the E/log diagram
