The corrosion potential of mild steel in a deaerated solution of pH = 2 is -0.64 V versus saturated Cu-CUSO, half-cell. The hydrogen overpotential (volts) for the same steel follows the relation 0.7 + 0.1 logi, where i = A/cm². Assuming that approximately all the steel surface acts as cathode, calculate the corrosion rate in mm/y.

A galvanic cell is based on the following half-reactions: In this cell, the copper compartment contains a copper electrode and [Cu2+] = 1.00 M, and the vanadium compartment contains a vanadium electrode and V2+ at an unknown concentration. The compartment containing the vanadium (1.00 L of solution) was titrated with 0.0800 M H2EDTA2, resulting in the reaction H2EDTA2(aq)+V2+(aq)VEDTA2(aq)+2H+(aq)K=?
