Fluorine (F2), the most electronegative element reacts with water in a different way compared to other halogens do. With excess water, fluorine reacts with water to produce hydrofluoric acid and oxygen gas in
the following reaction:
2F2(g) + 2H2O(1)→→4HF (1) + O2(g)
Calculate AHrxn for the process above from the following information:
2H2O(1)→ 2H2(g) + O2(g)
AH= +571.6 kJ (a)
2HF (g) → H2(g) + F2(g)
AH= +542.0 kJ (b)
Is the process exothermic or endothermic?
O Exothermic
O Endothermic
O Cannot be determined
O The entalphy change is zero
