Page 14 - Chemical equilibria Volume 4

xii Chemical Equilibria
The various volumes of the set will deal with the following topics:
– phase modeling tools: application to gases;
– modeling of liquid phases;
– modeling of solid phases;

– chemical equilibrium states;
– phase transformations;
– electrolytes and electrochemical thermodynamics;

– thermodynamics of surfaces, capillary systems and phases of small
dimensions.

Appendices in each volume give an introduction to the general methods
used in the text, and offer additional mathematical tools and some data.

This series owes a great deal to the feedback, comments and questions
from all my students are the Ecole nationale supérieure des mines
(engineering school) in Saint Etienne who have “endured” my lecturing in
thermodynamics for many years. I am very grateful to them, and also thank
them for their stimulating attitude. This work is also the fruit of numerous
discussions with colleagues who teach thermodynamics in the largest
establishments – particularly in the context of the group “Thermodic”,
founded by Marc Onillion. My thanks go to all of them for their
contributions and conviviality.

This fourth instalment in the series is devoted to the study of chemical
equilibria.
Chapter 1 describes transformations and chemical equilibria using
Donder’s affinity method. Equilibrium conditions are examined in enclosed
media, where one or more equilibrium states are present, and in open
systems. The chapter closes with a general look at azeotropic
transformations.

Chapter 2 is a general study of the properties of physical and chemical
equilibria. Thus, we examine the laws of displacement of equilibria under
the influence of various disturbances, and the Gibbs and Duhem phase laws.
Following a general study of indifferent states, the chapter goes on to
analyze the conditions of stability of equilibria.
