Rate of reaction
Question
- A. It decreases the collision frequency
- B. It increases the speed of particles
- C. It lowers the activation energy
- D. It decreases the energy of collisions
Answer
It increases the speed of particles
Explanation
The correct answer is It increases the speed of particles. This answer directly addresses the question: How does increasing the temperature affect 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 Collision Energy
Students often think that all collisions between particles result in a reaction, regardless of their energy.
Emphasize that only collisions with sufficient energy can lead to a reaction, and explain the concept of activation energy.
