Collision theory main parts

In order for particles to react, they must collide

When particles react, chemical bonds must be broken, this process requires energy (activation energy)

Particles must collide in the correct orientation.

Effect of increasing concentration and increasing pressure.

At higher concentrations(and pressures) there are more particles per unit volume and so the particles collide with a greater frequency and there will be a higher frequency of effective collisions.
