Collision theory is a principle of chemistry used to predict the rates of chemical reactions. It states that when suitable particles of the reactant hit each other with the correct orientation, only a certain amount of collisions result in a perceptible or notable change; these successful changes are called successful collisions.

Sep 12, 2022 · Use the postulates of collision theory to explain the effects of physical state, temperature, and concentration on reaction rates. Define the concepts of activation energy and transition state. Use the Arrhenius equation in calculations relating rate constants to temperature.
Collision theory explains why different reactions occur at different rates, and suggests ways to change the rate of a reaction. Collision theory states that for a chemical reaction to occur, the reacting particles must collide with one another. The rate of the reaction depends on the frequency of collisions.
Collision theory states that molecules must collide to react. For most reactions, however, only a small fraction of collisions produce a reaction.
