Question
- A. It is also exothermic
- B. It is endothermic
- C. It has no energy change
- D. It is irreversible
Answer
It is endothermic
Explanation
The correct answer is It is endothermic. This answer directly addresses the question: If the forward reaction of a reversible process is exothermic, what can be said about the reverse reaction? 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 Reversible Reactions
Students often confuse the products of a reversible reaction with the reactants, thinking they cannot revert back to the original substances.
Remember that in a reversible reaction, the products can react to form the original reactants. Practice interpreting word and symbol equations to reinforce this concept.
