chemical energy

[′kem·i·kəl ′en·ər·jē]
(physical chemistry)
Energy of a chemical compound which, by the law of conservation of energy, must undergo a change equal and opposite to the change of heat energy in a reaction; the rearrangement of the atoms in reacting compounds to produce new compounds causes a change in chemical energy.
