Stability of chemical equilibrium

The underlying idea is the restorative tendency of equilibrium, tending to counteract the effects of attempted changes on an original equilibrium system. This restorative tendency is associated with the stability of chemical equilibrium, and we therefore use the rigorous stability condition (8.13) to prove the above statement of Le Chatelier s principle in a general form. 

The stability of chemical equilibrium may be considered as a consequence of the stability of diffusion equihbrium. On the other hand, the stability of internal equilibria of a condensed system leads to independent conditions for diffusion stability, (c/. chap. XIX, 6). 

After the introduction of the concept of chemical equilibrium it is common to address the stability of chemical equilibrium, that is, the disturbance and subsequent re-establishment of a state of equilibrium within a chemical system. In upper secondary education (students age 16-18 years), changes in chemical equilibrium are usually studied from a semi-quantitative perspective, which in many countries is still dominated by the use of Le Chateher s principle. Although many variations of this principle exist, a common formulation is When a stress is applied to a system, the system responds in a way to try to relieve the stress.
