Question: The oxyanion of nitrogen in which it has the highest
The oxyanion of nitrogen in which it has the highest oxi-dation state is the nitrate ion (NO3-). The corresponding oxyanion of phosphorus is PO43-. The NO43- ion is known but is not very stable. The PO3- ion is not known. Account for these differences in terms of the bonding in the four anions.
Answer to relevant QuestionsUsing data from Appendix 4, calculate ΔHo, ΔSo, and ΔGo for the reaction Ns(g) + O2(g) → 2NO(g) Why does the NO formed in an automobile engine not readily decompose back to N2 and O2 in the atmosphere? Use bond energies (Table 13.6) to show that the pre-ferred products for the decomposition of N2O3 are NO2 and NO rather than O2 and N2O. (The N–O single-bond energy is 201 kJ/ mol.)
