Faradaic Reaction Involving One Adsorbed Species, No Desorption

1 Faradaic Reaction Involving One Adsorbed Species, No Desorption 

Let us suppose the simplest adsorption reaction involving one species that stays adsorbed, that is, there is no desorption  

This kinetic parameter is inversely proportional to the rate constant of the electrode process of adsorption. On the other hand, the adsorption pseudocapacitance reduces to 

To obtain the total impedance, the faradaic impedance, Eq. (5.19), must be inserted into the total impedance (Fig. 4.1b). The complex plane and Bode plots of the total impedance are as in Fig. 2.35. The circuit parameters R i and Cp depend on the potential, as illustrated in Fig. 5.1. The charge transfer resistance displays a minimum at Ep and its logarithm is linear with the potential further from the minimum, while the pseudocapacitance displays a maximum. These values at the potential Ep are
