Nitrogen can form several oxides. Their standard enthalpies of formation are listed as: $\Delta H_f^\circ[\text{NO}(g)] = +90\,\text{kJ mol}^{-1}$, $\Delta H_f^\circ[\text{N}_2\text{O}(g)] = +82\,\text{kJ mol}^{-1}$, $\Delta H_f^\circ[\text{NO}_2(g)] = +33\,\text{kJ mol}^{-1}$. Which of these statements are correct?
- A1, 2 and 3
- B1 and 2 only
- C2 and 3 only
- D1 only
