Collision Theory (17.5) Flashcards

- 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 related rate constants to temperature.
