Particle theory �“All matter is made up of tiny particles which are constantly in

Particle theory �“All matter is made up of tiny particles which are constantly in motion”

Particle theory �“All matter is made up of tiny particles which are constantly in

Particle theory �“All matter is made up of tiny particles which are constantly in motion” �The amount of motion particles have depends on the state they are in:

Particle theory �“All matter is made up of tiny particles which are constantly in motion” �The amount of motion particles have depends on the state they are in: - Solid: Particles have low-energy vibration movement only - Liquid: Particles have some movement energy, so can slide past eachother. - Gas: Particles have high energy and rapid movement in all directions.

Collision theory �“moving particles are constantly colliding with each other, but not all collisions

Collision theory �“moving particles are constantly colliding with each other, but not all collisions result in a reaction”

Collision theory �“moving particles are constantly colliding with each other, but not all collisions

Collision theory �“moving particles are constantly colliding with each other, but not all collisions result in a reaction” �For a successful collision to occur:

Collision theory �“moving particles are constantly colliding with each other, but not all collisions

Collision theory �“moving particles are constantly colliding with each other, but not all collisions result in a reaction” �For a successful collision to occur: - There must be a collision between the reactant particles.

Collision theory �“moving particles are constantly colliding with each other, but not all collisions

Collision theory �“moving particles are constantly colliding with each other, but not all collisions result in a reaction” �For a successful collision to occur: - There must be a collision between the reactant particles. - The particles must collide with sufficient energy to break forces holding particles together.

Collision theory �When there are more collisions, there is a likelihood there will be

Collision theory �When there are more collisions, there is a likelihood there will be more successful collisions, so the rate of reaction increases.
