Q: What states that chemical reactions occur when atoms, ions, or molecules collide? Read this paragraph and choose the correct option from the provided answers: Collision theory states that chemical reactions occur when atoms, ions, or molecules collide. In other words, these species need to make contact with one another in order for a reaction to take place. Based on this concept, along with a couple of other key points, collision theory helps to explain why certain factors will influence the rate of a chemical reaction. Choices: - disturbance theory - reaction theory - elemental theory - collision theory A:
(Answer)
collision theory
