Excerpt from An Introduction to the Principles of Physical: Chemistry From the Standpoint of Modern Atomistics Physical Chemistry is equivalent to five semester hours, it will usually be possible to take up in detail some of the more im portant thermodynamic derivations, and to facilitate this the derivations of practically all the thermodynamic equations em ployed in this book are given in the Appendix with the proper cross references in the body of the text. In many institutions, however, the short time available for the introductory course in Physical Chemistry makes it necessary to postpone most of the thermodynamics to more advanced courses. The arrangement of the text has been made with this state of affairs in mind and the discussion and use Of the Second Law in the body of the text is largely restricted to making clear the purely energetic char acter of thermodynamic reasoning, so that when a relation is given as a purely thermodynamic one the student may have a proper appreciation of the very dependable character of its foun dation, even though the details of all the derivations cannot be taken up in the class room. It is hoped also that the Appendix will be found useful as a convenient reference for the occasional inquiring mind which is not satisfied to take the thermodynamic equations on faith.
