(4) An intensive property is a bulk property, meaning that it is a physical property of a system that does not depend on the system size or the amount of material in the system.

G = - nFE Cell

The AG in the above equation is an extensive property, E cell is an intensive property. A negative E° means that the redox couple is a stronger reducing agent than the H + /H 2 couple. The amount of electricity required for oxidation or reduction depends on the stoichiometry of the electrode reaction. The amount of chemical reaction which occurs at any electrode during electrolysis by a current is proportional to the quantity of electricity passed through the electrolyte.
