Question

According to Le Chatelier's Principle, what happens to a system at equilibrium when itis subjected to a change in concentration, pressure or temperature?

• A. The system remains at equilibrium without any changes.
• B. The system will always favour the formation of reactants.
• C. The system will undergo a permanent change in state.
• D. The system shifts in the direction that opposes the change to re-establish equilibrium.

Answer 1

Answer:

D. The system shifts in the direction that opposes the change to re-establish equilibrium.

Le Chatelier's Principle states that when a system at equilibrium is subjected to a change in concentration, pressure, or temperature, it will shift in the direction that opposes the change to re-establish equilibrium Le Chatelier’s principles, also known as the equilibrium law, are used to predict the effect of some changes on a system in chemical equilibrium (such as the change in temperature or pressure). The principle is named after the French chemist Henry Louis Le Chatelier.
