According to Le Châtelier's principle, what would happen to a system at equilibrium if more of one compound in a reaction were added?

Multiple choices.

A. A system at equilibrium will stay at equilibrium even if conditions are upset.

B. A system will not be able to restore equilibrium if conditions are changed.

C. A system will go to completion if equilibrium conditions are changed.

D. A system whose equilibrium has been upset will shift to restore equilibrium Answer;

B. All concentrations would change.

Explanation;

-According to Le Châtelier's principle, if more of one compound in a reaction were added to a system at equilibrium then all concentrations would change.

-Le Chatelier's principle states that changes to an equilibrium system will result in a predictable shift that will counteract the change.

-Increasing the concentration of reactants will drive the reaction to the right, while increasing the concentration of products will drive the reaction to the left.
