No references found			Thermodynamic Potential It is known from thermodynamics that when entropy terms are neglected the heat of dissociation of an antioxidant may be expressed in terms of oxidation reduction potential as: [Delta] H = NFE (1) where H is heat of dissociation, N is the number of moles dissociated, F is Faraday's constant, and E is the potential for dissociation.
