Question
- A. It will shift towards the products.
- B. It will shift towards the reactants.
- C. It will remain unchanged.
- D. It will shift to the left.
Answer
It will shift towards the products.
Explanation
The correct answer is It will shift towards the products.. This answer directly addresses the question: In a closed system at equilibrium, if the concentration of a product is decreased, what effect will this have on the equilibrium position? It matches the approved Chemistry 8462 learning objective and the linked subtopic. The other options are incorrect because they either change the rate, catalyst, reversible reaction, equilibrium, or graph context, or they do not answer the exact point being tested.
Common mistake
Misunderstanding Equilibrium Shift
Students often think that decreasing reactant concentration will shift the equilibrium towards products instead of reactants.
Remember that according to Le Chatelier's Principle, decreasing the concentration of reactants will shift the equilibrium towards the side that produces more reactants to oppose the change.
