Key Principles of Collision Theory

Collisions Are Necessary for Reactions

For a chemical reaction to occur, reactant particles must collide. However, not all collisions result in a reaction.
Unsuccessful Collisions: Most collisions do not lead to a reaction. Particles may simply bounce off one another without any changes.
Successful Collisions: These occur only when two critical conditions are met:
1. Sufficient energy: particles must collide with energy equal to or greater than the activation energy ($E_a$), the minimum energy needed for a reaction to occur.
2. Correct Orientation: Particles must align in a specific way for the bonds to break and reform into new products.
