Chemical kinetics also provide an idea to make predictions about important reactions such as those that occur between gases in the atmosphere. It is a huge field that encompasses many aspects of physical chemistry. The book is designed to help the reader, particularly students, researchers, research scholars, scientists, chemists and industry fraternity of chemistry and allied fields; understand the mechanics and reactions rates. The selection of topics addressed and the examples, tables and graphs used to illustrate them are governed, to a large extent, by the fact that this book is aimed primarily at chemistry and allied science and engineering technologist. The objective of this book is to give academia, research scientists, research scholars, science and engineering students and industry professionals an overview of the kinetics quantities such as rates, rate constants, enthalpies, entropies, and volume of activation. This book also emphasizes how these factors are used in interpretation of the mechanism of a reaction. This book is based on the series of chapters written by different authors and divided into 15 chapters, each one succinctly dealing with a specific chemical kinetics and reaction mechanisms. The contents are widely encompassing as possible for chemical kinetic research field. The book critically compares the chemical kinetics and reaction mechanisms so that the most attractive options for chemistry (physical, organic and inorganic) research can be identified for academia, research scientists, research scholars, science and engineering students and industry professionals.
