Gibbs free energy change ($\Delta G$) is a thermodynamic quantity that measures the maximum reversible work obtainable from a system at constant temperature and pressure. It is essential in determining the spontaneity of a process, as a negative $\Delta G$ indicates a spontaneous reaction, while a positive $\Delta G$ suggests non-spontaneity. Understanding Gibbs free energy change helps connect chemical reactions to their energy dynamics, allowing for predictions about reaction favorability and equilibrium.
