- C. Particles must collide at high speed
- D. Particles must be of the same type
Answer
Particles must collide with sufficient energy
Explanation
The correct answer is Particles must collide with sufficient energy. This answer directly addresses the question: What is required for a chemical reaction to occur according to collision theory? 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 Theory
Students often think that all particle collisions result in a chemical reaction, not realizing that only certain collisions lead to reactions.
Emphasize that for a reaction to occur, particles must collide with sufficient energy and the correct orientation.
