The principle of detailed balance
WebbOnsager Reciprocal Relations and Detailed Balance Let the principle of detailed balance be valid. Then, in the linear approximation near equilibrium the reaction rates for the generalized mass action law are Therefore, in the linear approximation near equilibrium, the kinetic equations are : Webb20 juli 2024 · The reason given is: Although this mechanism at first sight appears reasonable, no actual process follows this mechanism because it violates the principle of detailed balance. According to this principle, at equilibrium the forward rate of each step is equal to the reverse rate of that step. Thus equilibrium cannot be maintained by this …

Organisms are non-equilibrium, stationary systems self-organized via spontaneous symmetry breaking and undergoing metabolic cycles with broken detailed balance in the environment. The thermodynamic free-energy (FE) principle describes an organism’s homeostasis as the regulation of biochemical work constrained …
WebbThis chapter treats the thermodynamic equilibrium of gases and radiation. According to the principle of detailed balance (Sect. 1.2), any reaction taking place within a thermal gas is exactly counterbalanced by its inverse reaction. Section 1.3 provides a proof of this principle for the special case of binary collisions. WebbDetailed Balance Absorption flux.

For this purpose, use the representation of the activity through the chemical potential: $${\displaystyle a_{i}=\exp \left({\frac {\mu _{i}-\mu _{i}^{\ominus … Visa mer The principle of detailed balance can be used in kinetic systems which are decomposed into elementary processes (collisions, or steps, or elementary reactions). It states that at equilibrium, each elementary … Visa mer A Markov process is called a reversible Markov process or reversible Markov chain if it satisfies the detailed balance equations. These equations require that the Visa mer For many systems of physical and chemical kinetics, detailed balance provides sufficient conditions for the strict increase of entropy … Visa mer Let the principle of detailed balance be valid. Then, for small deviations from equilibrium, the kinetic response of the system can be approximated as linearly related to its … Visa mer The principle of detailed balance was explicitly introduced for collisions by Ludwig Boltzmann. In 1872, he proved his H-theorem using this principle. The arguments in favor … Visa mer The microscopic "reversing of time" turns at the kinetic level into the "reversing of arrows": the elementary processes transform into their reverse processes. For example, the reaction transforms into and conversely.
