26 cze 2024 · I want to derive Gibbs Free Energy formula from 1st and 2nd law of thermodynamics. I saw some texts using T and P constant in derivation. I am confused about that. If n,P, T are constant then its about a specific state. Then what gibbs free energy actually imply?
18 cze 2024 · ΔG°: ΔG°, or standard Gibbs free energy change, is the difference in Gibbs free energy between the products and reactants under standard conditions (1 atm pressure and 298K). It predicts whether a reaction will be spontaneous or not.

18 cze 2024 · The change in free energy (−ΔG) for a reaction could be determined by measuring directly the amount of electrical work that the battery could do and then using the equation W max = −ΔG. However, the power of thermodynamics is that −Δ G can be calculated without having to build every possible battery and measure its performance.
