Question

le chateliers principle says that when changes are made to a system at equilibrium, the system shifts to (1 point)

oppose the change, and return to equilibrium

embrace the change and reach a new equilibrium

make more product, and complete the reaction

lower the temperature, and reach a higher equilibrium

Explanation:

Le Chatelier’s principle states that a system at equilibrium, when subjected to a change (in concentration, pressure, temperature, etc.), will shift its equilibrium position to oppose the change and re - establish equilibrium. The option “embrace the change...” is incorrect as the system opposes, not embraces. “Make more product...” is wrong because the shift depends on the type of change and doesn't always make more product. “Lower the temperature...” is incorrect as the response to temperature change depends on if the reaction is exothermic or endothermic and it's not a general rule of Le Chatelier’s principle. Only the first option correctly describes the principle.

Answer:

A. oppose the change, and return to equilibrium
