Abstracts
Relaxation process is the spontaneous transition of an isolated system from one to another macroscopicstate. It is assumed that the entropy increase associated with this process is a functional of dynamical variables (fluxes). This fact makes entropy production a dynamical variable. It is shown within Jaynes’ MaxEnt formalism that almost all possible microscopic fluxes are accompanied by maximal entropy production. Using Einstein’s formula for probability of fluctuation, we obtain that the probability of the change in entropy is proportional to the exponential function of the entropy change divided by the Boltzmann constant. This result is applied to the system close to the equilibrium and the well-known relationships between thermodynamic forces and fluxes are reproduced.
