In our reactor each
of the M species has an activity 
. We compute an activity aji of the i-substance in
the j-reaction as a difference of the total sums of chemical potentials for the
N products and L educts, which take part in the j- reaction 
. aj is the activity of
the j-reaction.
We search a solution
of the differential equation 
in the form of Euler’s
operator 
. ni is the equilibrium
concentration of the i-specie. Following the iteration process we reach the
start concentrations of the P elements (bl) with the global error of
10-7.
With help of program
complex "Kondesat" we compute equilibrium concentrations of species
for chosen systems in a dependence of the temperature, pressure and
concentration of a start substance. During the researches
we analyze the chemical potentials of individual reactions and simultan
reaction systems, calculate thermodynamic constants for the substances with aim
to investigate their thermochemical properties and account thermodynamic
functions for rest species.
