Faradaic admittance with reactant adsorption: Adsorption detection limits for redox systems with finite charge transfer rate

On basis of equations for the faradaic admittance given by Moreira and De Levie 8] the numerical data are presented which show the frequency dependence for cases with the finite charge transfer rate and various degrees of adsorption contribution. The reliability of diagnostic criteria for the adsorption detection is discussed and in some cases the resulting error in the k⁰ value (if the diagnostic test failed) is given.
