Description

Electrochemical Kinetics: Theoretical Aspects focuses on the processes, methodologies, reactions, and transformations in electrochemical kinetics.
The book first offers information on electrochemical thermodynamics and the theory of overvoltage. Topics include equilibrium potentials, concepts and definitions, electrical double layer and electrocapillarity, and charge-transfer, diffusion, and reaction overvoltage. Crystallization overvoltage, total overvoltage, and resistance polarization are also discussed.
The text then examines the methods of determining electrochemical reaction mechanisms, including examination of the overall electrode reaction and determination of the type of overvoltage and reaction kinetics. A list of frequently used symbols is also provided.
The book is a valuable reference for readers interested in the study of electrochemical kinetics.
