===Factors Affecting the Rate of Reaction===
There are several factors which affect the '''rate of reaction'''. These include:
*[[Temperature]] - The higher the [[temperature]] the faster the [[Chemical Reaction]]. [[Exothermic]] [[Chemical Reaction|reactions]] may speed up as the [[Reaction Mixture|reaction mixture]] becomes hotter.
*[[Concentration]] - The higher the [[concentration]] of [[reactant]]s the faster the [[Chemical Reaction]]. As [[reactant]]s are used they become less [[concentration|concentrated]] and the [[Chemical Reaction|reactions]] tend to slow down as it progresses.
*[[Pressure]] - The higher the [[pressure]] of [[gas]]eous [[reactant]]s the faster the [[Chemical Reaction]].
*[[Surface Area]] - The larger the [[Surface Area|surface area]] of a [[solid]] [[reactant]] the faster the [[Chemical Reaction]] as there is a greater [[area]] over which the different [[reactant]]s can interact.
*[[Catalyst]]s - [[Catalyst]]s can increase the '''rate of reaction''' by providing different reaction pathways.
The effects of [[temperature]], [[concentration]], [[pressure]] and [[Surface Area|surface area]] on '''rates of reaction''' can be explained by '[[Collision Theory]]'.
