Chemical stability
（重定向自Thermodynamic stability）
Chemical stability when used in the technical sense in chemistry, means thermodynamic stability of a chemical system.
Thermodynamic stability occurs when a system is in its lowest energy state, or chemical equilibrium with its environment. This may be a dynamic equilibrium, where individual atoms or molecules change form, but their overall number in a particular form is conserved. This type of chemical thermodynamic equilibrium will persist indefinitely unless the system is changed. Chemical systems might include changes in the phase of matter or a set of chemical reactions.
