A chemical oscillator is a complex mixture of reacting chemical compounds in which the concentration of one or more components exhibits periodic changes. They are a class of reactions that serve as an example of non-equilibrium thermodynamics with far-from-equilibrium behavior. The reactions are theoretically important in that they show that chemical reactions do not have to be dominated by equilibrium thermodynamic behavior.

Property Value
dbo:abstract
  • A chemical oscillator is a complex mixture of reacting chemical compounds in which the concentration of one or more components exhibits periodic changes. They are a class of reactions that serve as an example of non-equilibrium thermodynamics with far-from-equilibrium behavior. The reactions are theoretically important in that they show that chemical reactions do not have to be dominated by equilibrium thermodynamic behavior. In cases where one of the reagents has a visible color, periodic color changes can be observed. Examples of oscillating reactions are the Belousov–Zhabotinsky reaction (BZ reaction), the Briggs–Rauscher reaction, and the Bray–Liebhafsky reaction. (en)
  • Un oscilador químico es una mezcla compleja de compuestos químicos reactivos en los que la concentración de uno o más componentes exhibe cambios periódicos. Son una clase de reacciones que sirven como ejemplo de termodinámica de no equilibrio con un comportamiento lejos del equilibrio. Las reacciones son teóricamente importantes porque muestran que las reacciones químicas no tienen que estar dominadas por el comportamiento termodinámico de equilibrio. En los casos en que uno de los reactivos tenga un color visible, se pueden observar cambios de color periódicos. Ejemplos de reacciones oscilantes son la reacción de Belousov-Zhabotinsky (BZ), la y la . (es)
