Cyclic Voltammetry for an Electro-Adsorption Reaction (EAR)
Cyclic Voltammetry for an Electro-Adsorption Reaction (EAR)
This Demonstration shows a numerical simulation of the cyclic-voltammetric response for a one-step electro-adsorption reaction (+s⟷A,s+) involving the soluble species , with constant concentration in the electrolyte, together with the adsorbate and free sites at the electrode surface. The thermodynamics is described by the Frumkin isotherm. Cyclic voltammogram and surface coverage versus potential curve are plotted. You can experiment with the effects of electro-adsorption kinetics, the interaction parameter in the adsorbed phase, the electrolyte resistance, and the double-layer capacitive effects using the controls for the relevant dimensionless parameters.
