Specific adsorption and multistep heterogeneous kinetics

The adsorption of reaction intermediates constitutes the most widely known cause of inductive phenomena in low-frequency impedance studies. Corresponding kinetic models represent a total reaction that combines multiple 

Only adsorption and charge-transfer processes occur on a two- dimensional interface. 

Adsorption of the intermediate B obeys a Langmuir isotherm and is characterized by a surface coverage 6 with adsorbates forming only a monolayered, fixed number of equivalent adsorption sites, and no energetic interaction between adsorbed species occurs. 

The reactions are governed by heterogeneous kinetics with diffusion not playing a major role. 

The reaction rates are exponentially potential-dependent (and obey TafeTs Law) K. = k in mol/cm sec. The k. may also include, for
