The oxidation of ammonia is illustrated by the following equation:
4 NH3 (g) + 5 O2 (g) → 4 NO (g) + 6 H2O (g)
Calculate the enthalpy of reaction, ΔHRxn, based on the given standard heats of formation.
Use the molar bond enthalpy data in the table to estimate the value of
δ𝐻°rxn for the equation C2H4(g) + HBr(g) ⟶ C5H5Br(g)
