Gibbs Free Energy Change (ΔG) is a thermodynamic quantity that represents the maximum reversible work obtainable from a closed system at constant temperature and pressure. It indicates the spontaneity of a process: a negative ΔG means the process can occur spontaneously, while a positive ΔG indicates it is non-spontaneous. Understanding ΔG is crucial when evaluating reactions in various processes, including adsorption and ion exchange, as it helps predict whether or not these reactions will proceed under given conditions.
