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
