Question
- A. It decreases collision frequency.
- B. It has no effect on collision frequency.
- C. It increases collision frequency.
- D. It only affects the energy of collisions.
Answer
It increases collision frequency.
Explanation
The correct answer is It increases collision frequency.. This answer directly addresses the question: What effect does increasing concentration have on collision frequency? 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
Confusing Collision Concepts
Students often confuse collision frequency with collision energy, thinking that a higher frequency means higher energy.
Focus on understanding that collision frequency refers to how often particles collide, while collision energy is about the energy of those collisions. Use diagrams to visualize the differences.
