Consider a hypothetical ionic compound AB (comprised of A+ and B- ions).
Given the following enthalpy data and using a Born-Haber cycle calculation, predict ΔHlattice in kJ mol-1.
A (s)+ B (s) → AB (s) ΔH = -370 kJ mol-1
A (s)→ A (g) ΔH = 110 kJ mol-1
B (s)→ B (g) ΔH = 91 kJ mol-1
First ionization energy of A (gas phase) = 481 kJ mol-1
Electron affinity of B (taking into account it's exothermic, gas phase) = -323 kJ mol-1
