A Pij = P(Xt = j | Xt − 1 = i), and πi and πj are the equilibrium probabilities of being in states i and j, respectively. N ) A w The stoichiometric matrix is α {\displaystyle \nu \in Y}, The semi-detailed balance condition is sufficient for the stationarity: it implies that. w The Wegscheider conditions demonstrate that whereas the principle of detailed balance states a local property of equilibrium, it implies the relations between the kinetic constants that are valid for all states far from equilibrium. {\displaystyle \nu } K w α = 0 = γ + i j ( = Albert Einstein in 1916 used the principle of detailed balance in a background for his quantum theory of emission and absorption of radiation.[4]. {\displaystyle {\boldsymbol {\lambda \Gamma }}=0} = . ( Q , − for the rth elementary reaction; w The same condition is valid for the reversible Markov processes (it is equivalent to the "no net flow" condition). r Simulated annealing. r / 0 {\displaystyle \ln w_{r}^{+}-\ln w_{r}^{-}} The system of stoichiometric equations of elementary reactions is the reaction mechanism. In 1901, Rudolf Wegscheider introduced the principle of detailed balance for chemical kinetics. For {\displaystyle \beta _{r}=\beta _{ri}} 2 α λ r is convenient for the representation of dissipation for the mass action law. A stochastic process is time-reversible if the joint probabilities of the forward and reverse state sequences are the same for all sets of time increments { τs }, for s = 1, ..., k for any k: ⟶ i / w ρ Section 5. Lorentz H.-A. , w + This non-invariance may be caused by the spontaneous symmetry breaking. Recall that this means that π is the p. m. f. of X0, and all other Xn as well. A system of reactions with some irreversible reactions is a limit of systems with detailed balance when some constants tend to zero if and only if (i) the reversible part of this system satisfies the principle of detailed balance and (ii) the convex hull of the stoichiometric vectors of the irreversible reactions has empty intersection with the linear span of the stoichiometric vectors of the reversible reactions. i r {\displaystyle {\ce {A}}_{i}} 95 (2), 153–164. ( r {\displaystyle L_{ij}=L_{ji}} ( A For systems that obey the generalized mass action law the semi-detailed balance condition is sufficient for the dissipation inequality [25] There exist nonreciprocal media (for example, some bi-isotropic materials) without T and PT invariance. q d Reversible Chains. r i Many interesting Markov chains are reversible. ⁡ The principle of detailed balance can be used in kinetic systems which are decomposed into elementary processes (collisions, or steps, or elementary reactions). + k ) Boltzmann, L.

According to the generalized mass action law, the reaction rate for an elementary reaction is. In 1872, he proved his H-theorem using this principle. i r {\displaystyle \beta _{r}} θ Thus, the principle of detailed balance is a sufficient but not necessary condition for entropy increase in Boltzmann kinetics. A c − Reciprocal relations in irreversible processes. {\displaystyle \gamma _{ri}=\beta _{ri}-\alpha _{ri}} ) This is possible because a kinetic law is known and relations between the rates of the elementary processes at equilibrium can be transformed into relations between kinetic constants which are used globally. See also: A. Einstein (1917). The Michaelis–Menten–Stueckelberg Theorem. To describe dynamics of the systems that obey the generalized mass action law, one has to represent the activities as functions of the concentrations cj and temperature.
