In the context of chemical equilibrium, what happens when a system is disturbed?

When a system at chemical equilibrium is disturbed, it will respond by adjusting to counteract that disturbance. This principle is rooted in Le Chatelier's principle, which states that if an external change is applied to an equilibrium system, the system will respond by shifting in a direction that minimizes the effect of the change.

For example, if the concentration of products in a reaction is increased, the equilibrium will shift to favor the reverse reaction, thereby reducing the concentration of products. Similarly, if the temperature of the system is changed or if pressure is altered (in reactions involving gases), the system will shift in a way that helps to restore equilibrium.

This ability of the system to adjust ensures that the equilibrium can be re-established even after a disturbance occurs, highlighting the dynamic nature of chemical reactions and equilibria.
