VOLTAMMETRY OF ADSORBED MOLECULES - PART-2 - IRREVERSIBLE REDOX SYSTEMS

Information about the kinetics of reactions can readily be extracted f rom linear sweep voltammograms of adsorbates which show irreversible b ehavior if the adsorbates behave ideally. Factors which cause nonideal behavior include lateral inter actions between adsorbates, influence of solvent reorganization energies, and kinetic dispersion. The diffic ulties in extracting information on the kinetics of adsorbed redox sys tems which behave nonideally are discussed. Diagnostic criteria are pr ovided from which it may be determined which of the above phenomena, i f any, are effecting the voltammetric response.
