The first reaction in the Ostwald process for the production ofnitric 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 bondenergies.
b) Calculate ΔH^o (in kJ) for this reaction using standard heatsof formation.
c) Briefly explain why the value for ΔH^o, calculated usingaverage bond energies, is only considered to be an estimate of thestandard enthalpy change for the reaction
