Which statements regarding the collision model are true? A. Molecules must collide with one another for a chemical reaction to occur. B. Molecules must be aligned with specific orientation for collisions between them to result in chemical reactions. C. All collisions between molecules result in chemical reactions. D. Collisions between molecules that occur with more than a minimum amount of energy always result in chemical reactions. E. Molecules must collide both with a minimum amount of energy and with the appropriate orientation relative to each other to result in chemical reactions.
