Faradic redox reaction
WebSince such reactions are governed by Faraday’s law (i.e., the amount of chemical reaction caused by the flow of current is proportional to the amount of electricity passed), they are called faradaic processes. Electrodes at which faradaic processes occur are sometimes called chargetransfer electrodes. WebFeb 15, 2016 · Details. This Demonstration models the Faradaic response for a one-step redox reaction to a typical cyclic-voltammetry (CV) input signal.The reaction involves two soluble species, and , on a planar electrode (e.g., Pt electrode) in a quiescent electrolyte. Dimensionless notation is used for the sake of generality.
