Question
Use the Born Haber cycle to calculate the lattice energy of Na2O(s) from the following data. Ionization energy of Na(g
) = 485 kJ mol-1 Electron Affinity of O(g) for two electrons = 553 kJ mol-1 Energy to Sublime Na(s) = 109 kJ mol-1
Bond energy of O2 = 449 kJ mol-1 ArxnH for 2 Na(s) + 1/2 O2(g) -> Na2O(s) = -466 kJ mol-1
