This book presents a unified approach to three types of chemical transformations: homogeneous chemical reactions, which occur in a single phase (typically in liquid or gaseous form), heterogeneous reactions, which occur at the interface between two phases (usually solid with liquid or gas), and electrochemical reactions, which occur at the charged interface between two phases (usually solid with liquid and less commonly solid with gas).

Focus is primarily on the principles governing Chemical and Electrochemical Kinetic phenomena, that is, the study of the rates at which chemical and electrochemical reactions occur.

Since the rate of consumption or production of chemical species depends on the system in which the chemical or electrochemical reaction takes place, kinetic analysis is accompanied by the presentation of useful principles that describe homogeneous, heterogeneous, and electrochemical systems.
