### Collision Model and Activated Complex Model

Can someone please explain how the collision model and activated complex model account for the temperature dependence of reactions?

### Re: Collision Model and Activated Complex Model

So, the collision model is a model that requires reactants to collide with sufficient energy to form products, and an activated complex is the required energy needed to change the reactants to products. Since temperature is a measure of average kinetic energy, the temperature must be high enough for reactants to turn into products upon the reactant's collision. Collisions can happen, but if the required energy isn't present, then the products can't form.
