Created page with "==Key Stage 4== ===Meaning=== '''Activation energy''' is the amount of energy needed to begin a chemical reaction. ===About Activation Energy=== ===..."

New page

==Key Stage 4==
===Meaning===
'''Activation energy''' is the amount of [[energy]] needed to begin a [[Chemical Reaction|chemical reaction]].

===About Activation Energy===
====Foundation====
: [[Chemical Reaction|Chemical reactions]] can't take place unless there is enough [[energy]] to cause the [[reactant]] [[molecule]]s to [[collide]] and [[Chemical Reaction|react]].
: Different [[Chemical Reaction|reactions]] need different amount of '''activation energy''' to start.
: The '''activation energy''' can be reached by [[heating]] the [[mixture]] of [[reactant]]s until they have enough [[energy]] to [[Chemical Reaction|react]].
: Sometimes [[reactant]]s at [[Room Temperature|room temperature]] have enough [[energy]] to [[Chemical Reaction|react]]. If the [[mixture]] of [[reactant]]s was lower than [[Room Temperature|room temperature]] they might not have enough [[energy]] to begin reacting.
: Once the '''activation energy''' is reached the [[Chemical Reaction|reaction]] will continue as [[energy]] is released when [[Chemical Bond|chemical bonds]] form to make the [[product]]s.
====Higher====
: '''Activation energy''' is needed to allow the [[reactant]] [[molecule]]s to [[collide]] with one another hard enough to break the [[Chemical Bond|bonds]] holding them together. This allows new [[Chemical Bond|bonds]] to form making the [[product]].
