- D. Depends on pressure
Answer
Shift towards the reactants
Explanation
The correct answer is Shift towards the reactants. This answer directly addresses the question: In a closed system, if the temperature of an endothermic reaction is decreased, how will the equilibrium position change? 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
Misinterpreting Le Chatelier’s Principle
Students often think that changing a condition simply speeds up the reaction, not that it shifts the equilibrium position.
Explain that Le Chatelier’s Principle predicts a shift in the position of equilibrium to oppose the change, not a change in the overall reaction rate. Clarify that the system moves to restore the original balance of reactants and products, not just to react faster.
