The first reaction in the Ostwald process for the production of nitric acid involves the combustion of ammonia

4NH3 (g) + 5O2 (g) = 4NO (g) + 6H2O (g)

a) Estimate ΔH^o (in kJ) for this reaction using average bond energies.

b) Calculate ΔH^o (in kJ) for this reaction using standard heats of formation.

c) Briefly explain why the value for ΔH^o, calculated using average bond energies, is only considered to be an estimate of the standard enthalpy change for the reaction
