Enthalpy

Thermodynamic state function, generally measured in kJ/mole. In chemical reactions, the enthalpy change (DH) is related to changes in the free energy (DG) and entropyThermodynamic quantity which is a measure of the degree of disorder within any system. The lower the degree of order, the higher the entropy; for an increase in entropy, DS is positive. Entropy has the units of J/K per mole. (DS) by the equation:
