==Key Stage 4==
===Meaning===
A '''reaction profile''' is a simple [[graph]] showing the [[energy]] change which takes place as a [[Chemical Reaction|reaction]] progresses.

===About Reaction Profiles===
: '''Reaction profiles''' can show the [[Activation Energy|activation energy]] needed for a [[Chemical Reaction|chemical reaction]] to begin.
: The '''reaction profile''' can be used to show whether a [[Chemical Reaction|reaction]] is [[exothermic]] or [[endothermic]].

| style="height:20px; width:200px; text-align:center;" |The '''reaction profile''' for an [[exothermic]] [[Chemical Reaction|reaction]] can be identified by the fact that the [[product]]s have less [[energy]] than the [[reactant]]s.
| style="height:20px; width:200px; text-align:center;" |The '''reaction profile''' for an [[endothermic]] [[Chemical Reaction|reaction]] can be identified by the fact that the [[product]]s have more [[energy]] than the [[reactant]]s.
