===About Catalysts===
: [[Catalyst]]s provide a different [[Reaction Pathway|reaction pathway]] for the [[reactant]]s to form the [[product]]s.: [[Catalyst]]s can lower the [[Activation Energy|activation energy]] needed to start a [[Chemical Reaction]].

| style="height:20px; width:200px; text-align:center;" |The [[Activation Energy|activation energy]] is shown to be low in this [[Reaction Profile|reaction profile]] for an [[exothermic]] [[Chemical Reaction|reaction]] with a [[catalyst]].

: Since the [[particle]]s in the [[Reaction Mixture|reaction mixture]] will all have different amounts of [[energy]] (see [[Kinetic Theory]]), not all of them will have enough [[energy]] to [[Chemical Reaction|react]] when they [[collide]] (see [[Collision Theory]]). Adding a [[catalyst]] lowers this [[Activation Energy|activation energy]] so more [[particle]]s have enough [[energy]] to [[react]], increasing the [[Rate of Reaction|rate of reaction]].
