…showed last 75 words of 264 total…First of all, the particles of the reacting substance must collide with each other and, secondly, they need a certain amount of energy to break down the bonds of the particles to form new ones. If the collision between particles can produce sufficient energy (i.e. if they collide fast enough and in the right direction) a reaction will take place. The reaction however can be speeded up if the number of collisions is increased.
