Abstract:
The global level thermodynamic comprehension of the local thermodynamic equilibrium assumption of nonequilibrium thermodynamics is presented. How the Gibbs relation given by equilibrium thermodynamics also describes a passage on an irreversible path is demonstrated at the global thermodynamic level. Specifically it has been demonstrated that the Gibbs relation indeed also takes care of irreversibility for a spatially uniform system with internal source of irreversibility for example the chemical reactions at non-vanishing rates and the irreversibility originating in the gradients of intensities across the boundary of the system. Hence, thermodynamic functions appearing in Gibbs relation are those for equilibrium and nonequilibrium states. The former is the case when it is used to describe a passage through the succession of equilibrium states and the latter is the case while describing the the passage through the succession of nonequilibrium states, i.e. on irreversible trajectories. Thereby, it gets demonstrated that the scope of validity of the local thermodynamic equilibrium assumption of nonequilibrium thermodynamics is much wider than it has been understood so far.
