Collision Theory In a chemical reaction: - 1. Particles must collide 2. The collision must have enough energy within it, for the particles to reach the transition state and form products. 3. The particles must collide in the right orientation if products are to be formed. The more the number of collisions, the more the chance that the collisions will have enough energy to reach the top of the activation energy to form products. In general most of the collisions either never have enough energy to form products or the particles do not collide...
