Preface     xiii
                             Chapter 3 discusses the different aspects of the law of mass action and the
                           equilibrium constants associated therewith. A number of graphical
                           representations used in the study of  chemical equilibria are presented. In
                           turn, we examine pole diagrams and  equilibrium representations with
                           temperature,  with the generalization  of Ellingham  diagrams. The chapter
                           ends with a presentation of binary, ternary and quaternary diagrams of
                           chemical equilibria.

                             The fourth  and final chapter in this volume is  given over to the
                           determination, both experimentally and by computation, of the values of the
                           parameters  associated with chemical reactions. Thermochemistry for
                           enthalpy, the determination of the entropies, specific heat capacities and
                           Gibbs energy values ultimately lead to the determination of the equilibrium
                           constants. Analysis of the different thermodynamic tables and methods for
                           estimating unknown values enable us to proceed to the practical application
                           and finally computation of the equilibria by the equilibrium constant method
                           and minimization of Gibbs energy.
