===Meaning===
The '''chemical potential energy store''' is the [[Energy Store|energy store]] associated with [[chemical]]s and their ability to [[Chemical Reaction|react]] with one another, releasing [[energy]].
===About Chemical Potential Energy===
: '''Chemical Potential Energy''' is linked to the [[Potential Energy|potential energy]] needed to break the [[Chemical Bond|chemical bonds]] in the [[reactant]]s and the [[product]]s.
: The '''chemical potential energy store''' of an [[object]] is related to three important factors in a [[Chemical Reaction|chemical reaction]]:
*The [[mass]] of [[substance]]s that will [[react]]. The more [[mass]] of [[Reaction Mixture|reaction mixture]] the greater the '''chemical potential energy store'''.
*The strength of the [[Chemical Bond|chemical bonds]] in the [[reactant]]s.
*The strength of the [[Chemical Bond|chemical bonds]] in the [[product]]s.
The greater the difference between the strength of [[Chemical Bond|bonds]] in [[reactant]]s and [[product]]s the greater the change in '''chemical potential energy''' during a [[Chemical Reaction|chemical reaction]].
: There is no single equation for the '''chemical potential energy store''' as it depends on the [[chemical]]s which are [[Chemical Reaction|reacting]] with one another.
