Mass Transport in Butler-Volmer Equation

This lecture delves into the impact of mass transport on the Butler-Volmer Equation, focusing on the 'leveling' effect at extreme potentials. It explores the simplifications for small n using Taylor series and their application to the equation. The lecture also covers the implications of large n, highlighting the behavior of the equation under different conditions. The total overpotential and its components are thoroughly analyzed, shedding light on the interpretation of various regimes and their effects on current and potential. The Tafel analysis, electrochemical reaction coordinate diagrams, and the determination of standard rate constants are also discussed.
