Use the data in Table 25.6 for the exchange current density and transfer coefficient for the reaction

Question:

Use the data in Table 25.6 for the exchange current density and transfer coefficient for the reaction Fe3++ e"-7 Fe2+on platinum at 25°C to determine what current density would be needed to obtain an over potential of 0.30 Vas calculated from
(a) The Butler-Volmer equation, and
(b) The Tafel equation. Is the validity of the Tafel approximation affected at higher over potentials (of 0.4 V and more)?
