Web7 de mar. de 2016 · This is represented by TΔS. This energy cannot be used for useful purposes. Thus the total energy which can be obtained from a compound is the total energy ( ΔH) minus the TΔS term. This maximum useful energy that can be obtained from a compound is called Gibbs Free Energy (ΔG = ΔH-TΔS). Share Improve this answer …
