  The article sets forth comprehensive basics of thermodynamics of chemical
equilibrium as balance of the thermodynamic forces. Based on the linear
equations of irreversible thermodynamics, De Donder definition of the
thermodynamic force, and Le Chatelier's principle, new thermodynamics of
chemical equilibrium offers an explicit account for multiple chemical
interactions within the system. Basic relations between energetic
characteristics of chemical transformations and reaction extents are based on
the idea of chemical equilibrium as balance between internal and external
thermodynamic forces, which is presented in the form of a logistic equation,
containing only one new parameter. Solutions to the basic equation define the
domain of states of the chemical system, from true equilibrium to true chaos.
The new theory is derived exclusively from the currently recognized ideas and
covers equilibrium thermodynamics as well as non-equilibrium thermodynamics in
a unique concept.
