Equilibrium
In thermodynamics, equilibrium refers to the evolution condition of the “state” of a system and its surroundings in accordance with time. Technically, a system is said to be in equilibrium when neither its state nor that of the surroundings evolves with time. [1] In earth-bound systems, daily heat input from the sun punctuates the state of each thermodynamic system away from equilibrium, thus forcing chemical species to evolve. [8]
In simple terms, chemical species evolve according to the logic of chemical reactions. In general, for earth-bound systems, being isothermal-isobaric systems, changes in the Gibbs free energy are useful in indicating the conditions under which a chemical reaction will occur. The spontaneity rule for reactions is that if ΔG is positive a reaction will only occur if energy is supplied to force it away from the "equilibrium" position (i.e. when ΔG = 0). If ΔG is negative the reaction will proceed spontaneously to equilibrium. [9] The combined set of reactions in a system characterize the equilibrium state of the system at any given time.
Equilibriums, in general, can be punctuated, stable, meta-stable, undifferentiated, unstable, near-equilibrium, far-from equilibrium, quasi-equilibrium, or non-equilibrium, among other terms. [7]
Difficulty on application in human systems
In human thermodynamics, there currently is great debate and confusion as to how the thermodynamic concept of equilibrium applies to systems of evolving human molecules. The origin of most equilibrium theories trace their origin to the 1876 publication of American mathematical physicist Willard Gibbs’ 300-page treatise “On the Equilibrium of Heterogeneous Substances” [2] In the years to follow, economists and sociologists, such as Vilfredo Pareto, began to apply Gibbs’ equilibrium criterion to the modeling of economic systems and social systems.
In 1977, in contrast to this logic, Belgian chemist Ilya Prigogine proposed that the Gibbs' equilibrium method is not applicable to life and that evolving living systems, such as communities of people, are “far-from-equilibrium” systems. [3] In 1978, in opposition to Prigogine, Russian physical chemist Georgi Gladyshev proposed that evolving living systems are “quasi-equilibrium” systems. [4] Beyond this, others, culling from a mix of ecological thermodynamics and fluid mechanics (i.e. Bernard’s cells), model human systems in terms of distance from equilibrium: (a) the equilibrium state, (b) slightly away from equilibrium, (c) near-equilibrium, and (d) far-from-equilibrium. [5]
In modern terms, the confusion existent between most biochemistry textbooks, which model (internal bodily) biochemical reactions as Gibbs-like equilibrium reactions, and many recent physics models of human social systems (reactions between humans), which model evolution as a far-from-equilibrium Prigogine-like fluid dynamics system, has caused much mishap. Some, in recent years, being caught up in this mix of theories, have summarized the matter by stating that “life is made up of reactions in the near equilibrium realm and may not be so far from equilibrium as has been suggested.”
Economic thermodynamics
In terms of thermodynamic approach to equilibrium in economics, some define equilibrium such that the system, instead of evolving in time, simply changes it position in the space of macroscopic parameters, remaining on certain surface, the surface of state, singled out by the “equation of state”. [6]
