Question
- A. To increase the temperature of the reaction
- B. To provide energy to the reactants
- C. To lower the activation energy
- D. To change the products of the reaction
Answer
To lower the activation energy
Explanation
The correct answer is To lower the activation energy. This answer directly addresses the question: What is the primary function 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
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.
