If stress is applied to a system at equilibrium, the system shifts to relieve the stress. Le Chatelier's principle. This principle explains that when a change occurs in a system at equilibrium, it will adjust to counteract that change and restore balance.
Imagine you're trying to balance a seesaw with two friends on either side, but suddenly, one friend decides to move closer to the center. Just like this seesaw, when a change or "stress" is introduced to a balanced situation, adjustments need to be made to restore equilibrium. In Le Chatelier's principle, when a system at equilibrium experiences a change in concentration, temperature, or pressure, the system shifts in a direction that counteracts the stress to regain balance, similar to how you'd adjust your position on the seesaw to keep it level.
