00906 IUPAC Gold Book - cathodic transfer coefficient 10.1351/goldbook.C00906 C00906 current quantity 1 For a reaction with a single rate-determining step \[\frac{\alpha _{\rm{c}}}{\nu } = -\frac{R\ T}{n\ F}\ (\frac{\partial (\ln (|I_{\rm{c}}|))}{\partial E})_{T,p,c_{i},...}\] where \(\alpha _{\rm{c}}\) is the cathodic transfer coefficient (number), \(R\) is the gas constant, \(T\) is the thermodynamic temperature, and \(\nu \) the stoichiometric number giving the number of identical activated complexes formed and destroyed in the completion of the overall reaction as formulated with the transfer of \(n\) electrons. coefficient https://goldbook.iupac.org//terms/view/C01124 gas constant https://goldbook.iupac.org//terms/view/G02579 stoichiometric number https://goldbook.iupac.org//terms/view/S06025 thermodynamic temperature https://goldbook.iupac.org//terms/view/T06321 PAC, 1974, 37, 499.
