Although electron gain enthalpy of fluorine is less negative as compared to chlorine, fluorine is a stronger oxidizing agent than chlorine this is due to the net higher standard electrode potential of fluorine is attributed to its low enthalpy of dissociation of F – F bond and high hydration enthalpy of F-
