Rate of reaction
Question
- A. By increasingthe temperature of the reaction.
- B. By providinga pathway with lower activation energy.
- C. By increasingthe concentration of reactants.
- D. By changingthe products formed.
Answer
By providinga pathway with lower activation energy.
Explanation
The correct answer is By providinga pathway with lower activation energy.. This answer directly addresses the question: Why do catalysts increase the rate of 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 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.
