Chapter 19, Problem E19D.7(a)(choose chapter or problem)
When the overpotential is small, the current density is given by eqn 19D.4. Assume this to be the case, take the surface area of the electrode to be \(1.0 \mathrm{\ cm}^{2}\) , and calculate the effective resistance at \(25^{\circ} \mathrm{C}\) of the following electrodes: (i) \(\mathrm{Pt}, \mathrm{H}_{2} \mid \mathrm{H}^{+}\) , and (ii) \(\mathrm{Hg}, \mathrm{H}_{2} \mid \mathrm{H}^{+}\) . Hint: The resistance is given by the ratio of the potential to the current.
