Rate of reaction
Question
- A. The rate decreases.
- B. The rate remains constant.
- C. The rate increases.
- D. The rate fluctuates.
Answer
The rate increases.
Explanation
The correct answer is The rate increases.. This answer directly addresses the question: What happens to the rate of reaction as the temperature increases? 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 Activation Energy
Students often think that increasing temperature only increases the speed of particles without considering the effect on the proportion of particles that can overcome activation energy.
Emphasize that increasing temperature not only increases particle speed but also increases the number of particles with sufficient energy to react, thus raising the proportion of particles with energy equal to or greater than the activation energy.
