Consider the following chemical reaction: NH3(g) + 2 O2(g) → HNO3(aq) + H2O(l). Calculate the change in enthalpy (ΔH) for this reaction using Hess' law and the enthalpy changes for the reactions given below. (1a) 4 NH3(g) + 5 O2(g) → 4 NO(g) + 6 H2O(l); ΔH = -1166.0 kJ/mol (2a) 2 NO(g) + O2(g) → 2 NO2(g); ΔH = -116.2 kJ/mol (3a) 3 NO2(g) + H2O(l) → 2 HNO3(aq) + NO(g); ΔH = -137.3 kJ/mol
