Le Chatelier’s Principle

If a system is in equilibrium, then a change in any of the factors that determine its equilibrium conditions will cause the system to change in such a manner so as to reduce or counteract the effect created by the change. It is applicable to all physical and chemical equilibria.

For example, if the temperature of a system in equilibrium is increased, the system will behave in such a manner so as to reduce the impact of increased temperature.
