Abstract:
All thermodynamic processes can be characterized by magnitudes of both their rate (flux) and their driving force. However, if several thermodynamic processes are concurrent in a system, they can affect one another. As a result, the rate of each of the processes (the flux of each thermodynamic parameter) depends not only on its own thermodynamic force but also on the driving forces of all the other processes that occur in the system. Near thermodynamic equilibrium, similar linear relationships are also valid for elementary chemical processes as well as for stepwise processes where the rates are proportional to the difference between the thermodynamic rushes of the initial and final reaction groups. The underlying idea is that the rate of numerous interacting irreversible processes can be described by linear differential equations with constant coefficients. This principle appears to be very fruitful in considering numerous irreversible processes near the thermodynamic equilibrium of the system. If the flux of an irreversible process is affected by thermodynamic force of another irreversible process through the mediation of the coefficient, then the flux of process is also influenced by thermodynamic force through the mediation of the same coefficient. In the case of interacting chemical processes, this statement reflects the principles of detailed (intimate) equilibrium and mass balance of the reactants that underlie the concepts of chemical kinetics.
