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.
