Δ G ° has a positive value, so this is not a spontaneous process. Key Takeaways. The change in Gibbs free energy (Δ G) is the maximum amount of free energy available to do useful work. If Δ G > 0, the reaction is nonspontaneous in the direction written. If Δ G = 0, the reaction is in a state of equilibrium. palazzo stefano balbi genovaWebGibbs free energy, G amount of energy available to do work - indicates spontaneity equilibrium when deltaG = 0 (where H = TS) thermodynamics vs kinetics are separate!!! when a reaction is thermodynamically spontaneous, it has no bearing on how fast it goes. it only means that it will proceed eventually standard free energy change うどん 数値http://showard.sdsmt.edu/MET320/Handouts/EllinghamDiagrams/Ellingham_v22_Macro.pdf うどん 教科書
