Collision theory conditions
Collision theory conditions
Sufficient energy & correct orientation
Activation energy
Activation energy
Minimum energy required for reaction to proceed
Temperature increase effect on reactions
Temperature increase effect on reactions
More particles exceed activation energy; more collisions
