A chemistry student is required to determine the cathodic and anodic Tafel slopes for a reaction occurring at an electrode surface. The current density at the cathodic surface is known to be 1.8 mA/cm² and the current density at the anodic surface is known to be 1.2 mA/cm². The current potential relationship is given by the Tafel equation:log (i) = log (i0) + β_c * (E-E_c) for cathodic reactionlog (i) = log (i0) + β_a * (E-E_a) for anodic reactionWhere i is the current density, i0 is the exchange current density, β_c and β_a are the cathodic and anodic Tafel slopes respectively, E is the elect
