Reaction Kinetics Review and Transfer Coefficient

This video provides a quick review on kinetics of homogeneous and heterogeneous chemical reaction kinetics and their connection to electrochemistry.

Lesson 3A: Reaction Kinetics and Transfer Coefficient

Electrochemical Kinetic Relations

This video covers the derivations of the common electrochemcial kinetic relations including the current-overpotential relation and the Butler-Volmer equation

Lesson 3B: Useful Kinetic Relations in Electrochemistry

The Current-Overpotential Relation

The video develops some intuition for the thermodynamics, kinetics, and mass transfer involved in the electrochemistry through the current-overpotential relationship. This may be the most important video to watch and study. It uses a spreadsheet to show how different parameters impact the current response. You can download a copy of the spreadsheet to further explore each parameter at this link: Current-Overpotential Spreadsheet

Lesson 3C: The Current-Overpotential Relation

Overview of Advanced Electrochemical Kinetics

The following video gives an overview of inner and outer sphere reactions, Marcus theory, and multi-electron transfer reactions.
