Autokatalyse
WebA Darwinistic principle in catalysis? The term for the catalysis of an asymmetric, catalyzed reaction by its product is “asymmetric autocatalysis”. The enantiomeric excess of a self‐replicating syste... Autocatalytic reactions are those in which at least one of the products is a reactant. Perhaps the simplest autocatalytic reaction can be written [1] with the rate equations (for an elementary reaction) . This reaction is one in which a molecule of species A interacts with a molecule of species B. The A molecule … See more A single chemical reaction is said to be autocatalytic if one of the reaction products is also a catalyst for the same or a coupled reaction. Such a reaction is called an autocatalytic reaction. A set of chemical … See more Background The second law of thermodynamics states that the disorder (entropy) of a physical or chemical system and its surroundings (a closed system) must increase with time. Systems left to themselves become increasingly See more The initial amounts of reactants determine the distance from a chemical equilibrium of the system. The greater the initial concentrations the further the system is from equilibrium. As the initial concentration increases, an abrupt change in See more In 1995 Stuart Kauffman proposed that life initially arose as autocatalytic chemical networks. British ethologist Richard Dawkins wrote about autocatalysis … See more A chemical reaction of two reactants and two products can be written as $${\displaystyle \alpha A+\beta B\rightleftharpoons \sigma S+\tau T}$$ where the Greek letters are stoichiometric coefficients and the capital Latin letters represent chemical … See more It is possible to use the results from an autocatalytic reaction coupled with reaction–diffusion system theory to tailor the design of a thin … See more Asymmetric autocatalysis occurs when the reaction product is chiral and thus acts as a chiral catalyst for its own production. Reactions of this … See more
