Answer
Particles must collide with enough energy
Explanation
According to collision theory, for a reaction to occur, particles must collide with sufficient energy to overcome the activation energy barrier.
Common mistake
Collision Requirement Misconception
Students think that any collision between particles will automatically cause a reaction, ignoring the need for sufficient energy and correct orientation.
Explain that a reaction only occurs when colliding particles have enough kinetic energy to overcome the activation energy barrier and are properly oriented to form new bonds. Use the concept of activation energy and reaction profiles to illustrate that not all collisions lead to products.
