Sorry but you didn't proof your post and the last equation didn't post correctly. I have copied it here. /2O2+1/2H2→HNO3 ΔH= -174.1KJ
My best guess is that you meant 1/2N2 + 3/2O2 + 1/2H2 = HNO3 with delta H of -174.1 kJ but I don't know that and I'm hesitant to do all that work for nothing. Please repost your program and proof it to know it is correct.
Solve the heat combustion equation: 2N2+5O2→2N2O5 ΔH=? N2O5+H2O→2HNO3 ΔH= -76.6KJ H2+1/2O2→H2O ΔH= -285.8KJ 1/2N2+3/2O2+1/2H2→HNO3 ΔH= -174.1KJ
