16.6 Collision Theory For a simple reaction: A + B something Reactants must collide to react High concentration makes collisions more likely Collisions need to have a certain energy for the reaction to take place – This roughly translates to Arrhenius’ E a (activation energy)

Transition state theory Building on the idea that collisions need a certain energy (activation energy) Transition state: Partial bonds exist where bonds are to be formed Bond about to be broken become partial bonds The transition state is half-way between reactant and products
