Summary:
- Collision theory is a set of principles that states that the reacting particles can form products when they collide with one another provided those collisions have enough kinetic energy and the correct orientation.
- Particles that lack the necessary kinetic energy may collide, but the particles will simply bounce off one another unchanged.
- The figure below illustrates the difference.
- In the first collision, the particles bounce off one another and no rearrangement of atoms has occurred.
- The second collision
