Question
- A. catalysts are always gases.
- B. catalysts are included in the overall chemical equation.
- C. catalysts can be reused multiple times.
- D. catalysts increase the temperature of the reaction.
Answer
catalysts can be reused multiple times.
Explanation
The correct answer is catalysts can be reused multiple times.. This answer directly addresses the question: Which of the following statements about catalysts is true? 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 Catalysts
Students often think that catalysts are consumed in the reaction and therefore do not understand that they can be reused.
Remember that a catalyst is not used up in a reaction; it changes the rate of the reaction by providing an alternative pathway with lower activation energy.
