Abstract
The mathematical treatment of mass transport in tubular electrodes has been examined for the EC process when a reversible electrode charge transfer is followed by a reversible chemical reaction. The transition from fast chemical reaction to slow chemical reaction is investigated. The system of convective-diffusion equations, representing the physical phenomena, are solved using properties of the integral transform and numerical computation of the integral equation. The effects of the chemical equilibrium parameter, the axial velocity of the flow and the potential scan rate on theoretical current-potential curves are elucidated and a simple procedure to determine the chemical reaction rate constant is presented.
