Chemico: Chemical Reaction
The chemical field is unique in multiphysics. As explained in Part I of the book, it is still counted as a physical field in multiphysics, though chemical reactions are not counted as physical processes. In this chapter, basics of chemical reactions will be presented first to provide background knowledge for the chemical field. Then chemical kinetics will be introduced as it defines the governing equation of the chemical field. An example will be given to demonstrate the use of chemical kinetics for establishing the governing equation. The reaction rate coefficient is the key auxiliary relationship in the governing equation. The formulation of this coefficient and its dependence on various environmental factors will be discussed at last.
