In thermodynamics, chemical energy refers to energy associated with or derived from a chemical reaction or process.
Overview
The term "chemical energy", in thermodynamics, can refer types of energy, e.g. internal energy, free energy, enthalpy, entropy, bond energy, chemical potential, etc., of chemical reactions and processes. A loose definition of chemical energy refers to energy stored, released or absorbed in or from changes of chemical bonds and their associated changes in bond energy during chemical reactions. In short, chemical energy is the part of the energy of a substance that can be released by a chemical reaction. [1] Technically, to note, there is no exacting definition of chemical energy, but rather a one is led into lengthy discussions in chemical thermodynamics terms, unique to each reaction or process.
