Gibbs free energy (G) is a measure of the spontaneity of a chemical reaction. It is the chemical potential for a reaction, and is minimized at equilibrium. It is defined as G=H-TS where H is enthalpy, T is temperature, and Sis entropy. The chemical reaction that causes aluminum to corrode in air is given by 4A1+302 in which at 298 K, AHxn ASixn - 625.1 J/K. - 2Al2O3 H www - 3352 kJ and
