At the present, numerous kinetic theories are available to electrochemists in describing chemical reactions at the electrode. These exist in varying degree of complexity, ranging from simplistic empirical formulae to more rigorous models that account for microscopic physical phenomena pertiaining to the reactive species and their environment. However, experimental work documented in support of the validity and comparison between these theories is scarce. This is largely due to difficulty in attaining and controlling the experimental conditions where applicability of the theories break down. As such, the current work utilizes state-of-the-art · electrochemical experimental techniques in order to test some of the most prominent electrode kinetics theories via comparison to simulations. This is done with the aim of identifying their limitations and providing new insight into fundamental mechanistic processes that occur during an electrochemical reaction.
