Released energy of exergonic reaction
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation.
Chemical reactions are determined by the laws of thermodynamics. Reactions can proceed by themselves if they are exergonic, that is if they release energy. The free energy of an exergonic chemical reaction is composed of two different thermodynamic quantities, enthalpy and entropy
|DG||Difference of Released energy (J)|
|DH||Difference of Enthalpy (J)|
|DS||Difference of Entropy (J/K)|
