  • Ans. 

    Le Chatelier's principle states that a system at equilibrium will respond to a stress by shifting to counteract the stress and restore equilibrium.

    • If a stress is applied to a system at equilibrium, the system will adjust to minimize the effect of the stress.

    • Changes in concentration, pressure, or temperature can cause a shift in equilibrium.

    • For example, if more reactants are added to a system at equilibrium, the system ...
