A chemical reaction can be reversed if the energy of the products exceeds the activation energy threshold.
A chemical reaction is a process, typically involving the breaking or making of interatomic bonds, in which one or more substances are changed into others.
A chemical reaction requires an energy called activation energy to occur. This energy is the energy needed to be surpassed before a chemical reaction can occur.
However, the reaction can be reversed if the energy of the products exceeds the activation energy threshold.
