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
