Autocatalytic reaction

中文百科

自催化反应 Autocatalysis

(重定向自Autocatalytic reaction)
自催化反应中产物浓度的双弯曲函数变化
The Lotka-Volterra equation is isomorphic with the predator prey model and the two reaction autocatalytic model. In this example baboons and cheetahs are equivalent to two different chemical species in autocatalytic reactions.
The Brusselator in the unstable regime. A=1. B=2.5. X(0)=1. Y(0)=0. The system approaches a limit cycle. For B<1+A the system is stable and approaches a fixed point.

自催化是指一个化学反应所生成之产物为该反应之催化剂。

若一组化学反应中一部分反应的产物足以催化其他反应,使得整组化学反应可自我供应能量和『食物分子』,则此组反应可称作集体自催化(collectively autocatalytic)(参见en:autocatalytic set)

(重定向自Autocatalytic reaction)
Sigmoid variation of product concentration in autocatalytic reactions
The Lotka-Volterra equation is isomorphic with the predator prey model and the two reaction autocatalytic model. In this example baboons and cheetahs are equivalent to two different chemical species in autocatalytic reactions.
The Brusselator in the unstable regime. A=1. B=2.5. X(0)=1. Y(0)=0. The system approaches a limit cycle. For B<1+A the system is stable and approaches a fixed point.

A single chemical reaction is said to have undergone autocatalysis, or be autocatalytic, if one of the reaction products is also a reactant and therefore a catalyst in the same or a coupled reaction. The reaction is called an autocatalytic reaction.

The rate equations for autocatalytic reactions are fundamentally nonlinear. This nonlinearity can lead to the spontaneous generation of order. A dramatic example of this order is that which is found in living systems. This spontaneous order creation seems to contradict the Second Law of Thermodynamics. This contradiction is resolved when the disorder of both the system and its surroundings are taken into account.
