Question
- A. The equilibrium shifts towards products and the reaction rate increases.
- B. The equilibrium shifts towards reactants and the reaction rate decreases.
- C. The equilibrium shifts towards products and the reaction rate decreases.
- D. The equilibrium shifts towards reactants and the reaction rate increases.
Answer
The equilibrium shifts towards products and the reaction rate increases.
Explanation
The correct answer is The equilibrium shifts towards products and the reaction rate increases.. This answer directly addresses the question: If a reversible reaction is endothermic in the forward direction, how does increasing the temperature affect the equilibrium position and the reaction rate? 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
Confusing Temperature Effects
Students often confuse the effects of temperature changes on equilibrium position with those on reaction rate.
Focus on understanding that temperature changes affect the position of equilibrium by favouring either the endothermic or exothermic direction, while reaction rate changes are influenced by temperature but do not indicate equilibrium shifts.
