The rate constants are given for the model presented in Scheme 1. Forward and backward rate constants are α and β, respectively, and follow exponential voltage dependence as α₀ = α₀₀exp(z_0fV_mF/RT) and β₀ = β₀₀exp(z_0bV_mF/RT). The k₀ column gives each of the rates at 0 mV, and the z_k column indicates the equivalent valence in electronic charge units assigned to the transition. F is the Faraday constant, Vm is voltage, R is the universal gas constant, and T is the temperature in Kelvin.
