==Key Stage 4==
===Meaning===
[[Collision Theory]] is a [[Scientific Theory|scientific theory]] which [[explain]]s that [[Chemical Reaction|reaction]]s take place via the [[collision]] of [[particle]]s of [[reactant]]s.

===About Collision Theory===
: [[Collision Theory]] is based on the [[Kinetic Theory]] which [[explain]]s the motion of [[particle]]s in [[matter]].
: In [[Collision Theory]] [[particle]]s are said to [[collide]] with one another and that if two [[reactant]]s in a [[Chemical Reaction|reaction]] [[collide]] with enough [[energy]] this will cause them to [[Chemical Reaction|react]].

===Temperature and Collision Theory===
[[Kinetic Theory]] [[explain]]s how increasing the [[temperature]] of a [[substance]] causes the [[particle]]s to gain more [[Kinetic Energy|kinetic energy]] so they travel faster. When [[particle]]s travel faster (due to higher [[temperature]]s) they [[collide]] with more [[energy]] and they [[collide]] more frequently (more often). This means at higher [[temperature]]s [[particle]]s of the [[reactant]]s are more likely to [[collide]] with each other and they are more likely to have enough [[energy]] to [[Chemical Reaction|react]] when they do. This increases the [[Rate of Reaction|rate of reaction]].

===Pressure and Collision Theory===
The [[Particle Model]] explains how increasing the [[pressure]] on a [[gas]], and compressing it, causes the [[particle]]s in that [[gas]] to [[collide]] more frequently (more often). This means at higher [[pressure]]s the [[particle]]s of [[reactant]]s will [[collide]] more often, increasing the chances of them [[Chemical Reaction|reacting]].
