Rationalize the following lattice energy values:
Answer to relevant QuestionsThe lattice energies of FeCl3, FeCl2, and Fe2O3 are (in no particular order) –2631 kJ/ mol, –5339 kJ/ mol, and –14,774 kJ/ mol. Match the appropriate formula to each lattice energy. Consider the following reaction: A2 + B2 → 2AB ΔH = –285 kJ The bond energy for A2 is one- half the amount of the AB bond energy. The bond energy of B2 = 432 kJ/ mol. What is the bond energy of A2? Use the following standard enthalpies of formation to estimate the NOH bond energy in ammonia. Compare this with the value in Table. N(g) 472.7 kJ/ mol H(g) 216.0 kJ/ mol NH3(g) –46.1 kJ/ mol Benzene (C6H6) consists of a six-membered ring of car-bon atoms with one hydrogen bonded to each carbon. Draw Lewis structures for benzene, including resonance structures. Order the following species with respect to the carbon– oxygen bond length (longest to shortest): CO, CO2, CO32-, CH3OH What is the order from the weakest to the strongest carbon–oxygen bond?
