Voltammetric waveshapes measured in flowing systems: Mass transport-limited tafel analysis of some nonsimple systems

Analytical theory is presented which allows rigorous mass transport‐corrected Tafel analysis for the reversible electrode processes (1) 2B ⇄ A2 + 2e− and (2) B2 ⇄ 2A + 2e− occurring at electrodes in flowing systems. Predictions are compared with the conclusions of numerical finite‐difference modelli...

Zusammenfassung:Analytical theory is presented which allows rigorous mass transport‐corrected Tafel analysis for the reversible electrode processes (1) 2B ⇄ A2 + 2e− and (2) B2 ⇄ 2A + 2e− occurring at electrodes in flowing systems. Predictions are compared with the conclusions of numerical finite‐difference modelling for both wall‐jet and channel flow cell geometries. Exceillent agreement is found.
