Example 1: The exchange current densities for a hydrogen-evolution reaction on three different metals are 5x10* A/cm?, 3x107 A/cm², and 5×10" A/cm², 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.
