: When [[particle]]s have a large [[Kinetic Energy|kinetic energy]] during a [[collision]] they are more likely to have enough [[energy]] to break the [[Chemical Bond|chemical bonds]] holding [[atom]]s in the [[molecule]]s together.
====Pressure and Chemical Reactions====
: When the [[pressure]] of a [[substance]] is increased it causes the [[particle]]s [[collide]] more often.
: When [[particle]]s [[collide]] more often it means a greater chance of the [[Chemical Bond|chemical bond]]s breaking and [[atom]]s rearranging into new [[compound]]s.
