Calculate the corrosion rate of zinc in oxygen-free acid, pH = 3; if the reaction is:
Zn + 2H+ = Zn2+ + H2
eo (Zn/Zn2+) = -0.78 V; eo (2H+/H2) = 0.00 V; aZn2+ = 10-4;
io (Zn/Zn2+) = 10-5 A m-2; io (2H+/H2 on Zn) = 10-3 A m-2;
ba = 0.05 V dec-1 bc = -0.10 V dec-1; pH2 = 1.0 atm.
Please provide a labeled graph.
Would really appreciate the help!
