- C. They have no effect
- D. They double it
Answer
They decrease it
Explanation
The correct answer is They decrease it. This answer directly addresses the question: How do catalysts affect the activation energy of a 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
Ignoring Catalyst Role
Students often forget that catalysts are not consumed in the reaction and can be reused.
Remember that catalysts facilitate reactions without being used up, allowing them to be reused multiple times.
