According to the second law of thermodynamics, for systems reacting at fixed temperature and pressure without input of non-Pressure Volume (PV) work, there is a general natural tendency to achieve a minimum of the Gibbs free energy. A quantitative measure of the favorability of a given reaction under these conditions is the change ΔG (sometimes written "delta G" or "dG") in Gibbs free energy that is (or would be) caused by t…
