The Electrode Reaction subnode defines the electrode kinetics for the charge transfer reaction that occurs between the electrolyte and the electrode on the surface of a non-porous electrode. A default node is added where the electrode kinetics can be set up for the charge transfer reaction. The Electrode Reactions subnode is added by default to the Electrode Surface in the Electroanalysis Interface. You can also add it from the context menu (right-click the parent node) or from the Physics toolbar, Attributes menu.

Except for the Electroanalytical Butler-Volmer settings described below, see the Electrode Reaction node for information about the other settings.

The Electroanalytical Butler-Volmer is a concentration dependent kinetics expression based on a Heterogenous rate constant k0 (SI unit: m/s), the Cathodic transfer coefficient ac (dimensionless) and the reaction coefficients settings on the Stochiometric Coefficients section by which cred and cox are determined.
