6. Conclusion

This article aims to lay the conceptual and mathematical foundations of chemical thermodynamics (seen as the part of thermodynamics dedicated to the study of the properties of matter).

It touches on a number of themes that readers will find extended in other articles in the collection. For example :

• this article lays the foundations for writing energy and entropy balances, and mentions exergy balances. Readers interested in the subject of irreversibility analysis of chemical and energy processes can then turn to the articles dealing with exergy analysis of processes;

• It also deals with thermodynamic equilibria (chemical, polyphasic, osmotic) and, in particular, attempts to open the way to understanding pure-body phase diagrams represented in the (P, T), (P, v), (h, s), (T, s) and (P,...
