Heat of reaction and heat of formation will be the same in I. 1/2 N2( g)+O2( g)→NO2( g)\quad 1 / 2 \mathrm{~N}_2(\mathrm{~g})+\mathrm{O}_2(\mathrm{~g}) \rightarrow \mathrm{NO}_2(\mathrm{~g}) II. Xe(g)+2 F2( g)→XeF4( g)\quad \mathrm{Xe}(\mathrm{g})+2 \mathrm{~F}_2(\mathrm{~g}) \rightarrow \mathrm{XeF}_4(\mathrm{~g}) III. N2( g)+O3( g)→N2O3( g)\mathrm{N}_2(\mathrm{~g})+\mathrm{O}_3(\mathrm{~g}) \rightarrow \mathrm{N}_2 \mathrm{O}_3(\mathrm{~g}) IV. C(\mathrm{C}( diamond )+O2( g)→CO2( g))+\mathrm{O}_2(\mathrm{~g}) \rightarrow \mathrm{CO}_2(\mathrm{~g})
