?Use the data in Table 19D.1 for the exchange-current density and transfer coefficient
Chapter 19, Problem E19D.4(a)(choose chapter or problem)
Use the data in Table 19D.1 for the exchange-current density and transfer coefficient for the reaction \(2 \mathrm{H}^{+}+2 \mathrm{e}^{-} \rightarrow \mathrm{H}_{2}\) on nickel at \(25^{\circ} \mathrm{C}\) to identify the current density needed to obtain an overpotential of 0.20 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.
