For a reaction with a single rate-determining step $\frac{\alpha _{\text{c}}}{\nu } = -\frac{R\ T}{n\ F}\ (\frac{\partial (\ln (|I_{\text{c}}|))}{\partial E})_{T,p,c_{i},...}$ where $$\alpha _{\text{c}}$$ is the cathodic transfer @C01124@ (number), $$R$$ is the @G02579@, $$T$$ is the @T06321@, and $$\nu$$ the @S06025@ 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.
