A student wants to calculate the corrosion rate of a zinc electrode in contact with a copper electrode, with a measured current of 0.5 amperes and a surface area of 2 cm². Given that the standard reduction potentials for copper and zinc electrodes are +0.34 V and -0.76 V, respectively, what is the corrosion rate of the zinc electrode in millimeters per year? (Assume a density of 7.14 g/cm³ for zinc and a Faraday constant of 96,500 coulombs per mole).
