What occurs when any conditions of a reversible reaction change?

When the conditions of a reversible reaction change, the system responds to counteract that change, which is aligned with Le Chatelier's principle. This principle states that if an external change is applied to a system at equilibrium, the system will adjust itself to minimize that change and re-establish equilibrium.

For instance, if the concentration of reactants is increased, the system may shift towards the products to reduce that concentration. Similarly, if the temperature or pressure is altered, the system will respond by shifting the equilibrium position accordingly to counteract the effect of those changes. This behavior highlights the dynamic nature of chemical equilibria and how they strive for balance in response to external influences.
