Use the data in Table 19D.1 for the exchange-current density and transfer coefficient for the reaction Fe3+ + e− → Fe2+ on platinum at 25 °C to identify the current density needed to obtain an overpotential of 0.30 V as calculated (i) by using the Butler–Volmer equation, and (ii) by assuming that the current is entirely anodic. Comment on the validity of the latter assumption.
Significant evolution or deposition occurs in electrolysis only if the overpotential exceeds about 0.6 V. To illustrate this criterion calculate the effect that increasing the overpotential from 0.40 V to 0.60 V has on the current density in the electrolysis of 1.0 m NaOH(aq), which is 1.0 mA cm−2 at 0.4 V and 25 °C. Take α = 0.5. Hint: Assume that the current is entirely anodic.
