The collision theory explains reaction rates in terms of
size of the product
frequency of collision of the reactants
size of reactant
frequency of collision of the products
Explication
Collision theory is the theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another.
