The Phase Rule


IN the preface to this book the author says:— “My idea is that all qualitative experimental data (referring to chemical equilibrium) should be presented as particular applications of the Phase Rule and the Theorem of Le Chatelier, while the guiding principles for the classification of quantitative phenomena should be the Mass Law and the Theorem of van't Hoff. In this book I have tried to present the subject of qualitative equilibrium from the point of view of the Phase Rule and of the Theorem of Le Chatelier, without the use of mathematics.”

The Phase Rule.

By Wilder D. Bancroft. Pp. viii + 255. (The Journal of Physical Chemistry, Ithaca, New York, 1897.)
