JEE Main Chemistry question

Born-Haber cycle may be used to calculate

(A)Electronegativity
(B)Mass number
(C)Oxidation number
(D)Electron affinityCorrect

Answer: (D)

Solution

The Born-Haber cycle links the enthalpy of formation of an ionic solid to sublimation, dissociation, ionisation, electron-gain, and lattice enthalpies: Δ = S + ½D + I + Δ + U. If all other terms are known from independent experiments, the cycle can be solved
