?The transfer coefficient of a certain electrode in contact with \(\mathrm{M}^{2+}\) and
Chapter 19, Problem E19D.1(b)(choose chapter or problem)
The transfer coefficient of a certain electrode in contact with \(\mathrm{M}^{2+}\) and \(\mathrm{M}^{3+}\) in aqueous solution at \(25^{\circ} \mathrm{C}\) is 0.42. The current density is found to be \(17.0 \mathrm{\ mA} \mathrm{\ cm}^{2}\) when the overpotential is 105mV. What is the overpotential required for a current density of \(72 \mathrm{\ mA} \mathrm{\ cm}^{2}\) ? Hint: See hint to Exercise E19D.1(a).
