The object of the author of this textbook is to provide a work of a less advanced and detailed nature than the classic volume of Lewis and Randall, and at the same time to clarify certain fundamental principles with the view of making the subject one of real utility to the practical chemist. Thus, since most measurements refer to reactions at constant pressure, the advantage is urged of employing the criterion of zero free energy change at constant temperature, instead of zero maximum work of a process at constant volume and temperature, since the former is true of any reaction whatsoever.
