The change in free energy of the reaction (ΔG) is indicative of how far and in what direction a reaction will progress. A negative value of ΔG indicates that the reaction is spontaneous and will proceed forward, while a positive value of ΔG indicates that the reaction is non-spontaneous and will not proceed forward unless energy is inputted into the system.
