- B. It changes the rate of the reaction without beingused up.
- C. It decreases the concentration of reactants.
- D. It alters the products formed in the reaction.
Answer
It changes the rate of the reaction without beingused up.
Explanation
The correct answer is It changes the rate of the reaction without beingused up.. This answer directly addresses the question: What is the role of a catalyst in a chemical 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
Misunderstanding Catalyst Function
Students often think that catalysts are consumed in the reaction.
Remember that catalysts speed up reactions without being used up, allowing them to be reused in multiple reactions.
