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 ΔH_lattice 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
