This course provides the thermodynamic tools for understanding electrochemical reactions and devices. Starting from the concept of the electrochemical potential of charged species, this course will cover the thermodynamic relationships associated with electrochemical cells and various devices such as batteries and sensors. The potential distribution across electrified metal|electrolyte interfaces will also be discussed.
This course will enable you to understand the kinetics of electron transfer reactions at the electrode|electrolyte interface. In Level 2 - Equilibrium Electrochemistry, the thermodynamics of electrochemical cells and the potential distribution across the electrode|electrolyte interface were discussed. Out of equilibrium, it will be shown how the faradaic current is directly related to the kinetics of the electrochemical process. The elementary steps controlling the rate of the reaction, namely the interfacial electron transfer and the mass transport to the electrode surface, will be discussed in detail. Conventional electrochemical measurements such as cyclic voltammetry, chronoamperometry and rotating disc electrode will be introduced.
