What is Effective Collisions?

Effective collisions are molecular collisions that result in a chemical reaction, occurring when the colliding particles possess sufficient energy (at or above the activation energy) and the correct geometric orientation. Not all collisions between reactant molecules lead to products; only those meeting both the energy and orientation requirements are considered effective. The fraction of effective collisions determines the rate of a chemical reaction.
