What states that chemical reactions occur when atoms, ions, or molecules collide?
elemental theory
disturbance theory
reaction theory
collision theory
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.
