The exchange current densities for a hydrogen-evolution reaction on three different metals are 5x10 Aem, 3x10" A/cm', and 5x10" A/cm', respectively. Calculate the current densities and the polarization resistances if the reactions proceed at n = -0.08 V versus SHE. The electrode surface area is 1 cm and a = 0.5.
