Chemical kinetics is a branch of chemistry and is also known as reaction kinetics. It is associated with studying the rates of chemical processes and certain factors, like concentration and temperature, which affect the reaction rate. These studies help in tracing the mechanism progress with appropriate evidences at each stage. This book especially targets the students and practitioners in the field of physical science to gain comprehensive knowledge regarding reaction kinetics and its mechanism. The subjects discussed in this book and examples used to demonstrate have been driven by the principle that they are understandable to any reader with basic understanding of physical science. Even the graphs and tables used to support the content are of professional understanding. This book is a rich and valuable account of information for the reference of scientists, technologists, students and professionals engaged in this field. It has been written in a compact, self-descriptive and comprehensive manner by experts of the field.
