WebJan 15, 2024 · The functions A and G are oftentimes referred to as free energy functions. The reason for this is that they are a measure of the maximum work (in the case of Δ A) or non p-V work (in the case of Δ G) that is available from a process. To show this, consider the total differentials. First, consider the differential of A. d A = d U − T d S − ...
