Question
- A. A reaction that can only proceed in one direction
- B. A reaction in which products can react to make the original reactants
- C. A reaction that occurs at a constant temperature
- D. A reaction that releases energy only
Answer
A reaction in which products can react to make the original reactants
Explanation
The correct answer is A reaction in which products can react to make the original reactants. This answer directly addresses the question: What is a reversible 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
Energy transfer symmetry
Students think the forward and reverse reactions transfer different amounts of energy, assuming the exothermic direction releases more energy than the endothermic direction absorbs.
Explain that the magnitude of energy change is the same for both directions; the forward reaction releases the same amount of energy that the reverse reaction absorbs, so the total energy change over a full cycle is zero.
