A copper rod with a surface area of 5 cm² is coupled with an iron rod with a surface area of 10 cm² to form a galvanic cell. When the circuit is closed, the current flows for 2 hours and the weight loss of the iron rod was found to be 0.58 g. Determine the corrosion rate of the iron rod in millimeters per year (mm/yr) assuming a density of 7.86 g/cm³ for the iron.
