An important step in the synthesis of nitric acid is the conversion of ammonia to nitric oxide.      4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(g) Calculate ΔH°rxn for this reaction. ΔH°f [NH3(g)] = –45.9 kJ/mol ΔH°f [NO(g)] = 91.3 kJ/mol  ΔH°f [H2O(g)] = –241.8 kJ/mol Write out your calculations and answers clearly, with all numbers labeled correctly, on a piece of paper.  Right after submitting your exam, upload your photos to the Assignment Box, “Calculations for Exam 4 (Chapter 5 and 6)”
