Question

Use the Born-Haber cycle to calculate the lattice energy of MgO (s) given the following data:
         ?H(sublimation) Mg = 130 kJ/mol
         I1 (Mg) = 738.1 kJ/mol
         I2 (Mg) = 1450 kJ/mol
         Bond energy (O=O) = 498.7 kJ/mol
         EA (O) = 141 kJ/mol
         EA (O Use the Born-Haber cycle to calculate the lattice energy of MgO (s) given the following data:
         ?H(sublimation) Mg = 130 kJ/mol
         I1 (Mg) = 738.1 kJ/mol
         I2 (Mg) = 1450 kJ/mol
         Bond energy (O=O) = 498.7 kJ/mol
         EA (O) = 141 kJ/mol

Explanation / Answer

Lattice energy= Heat of formation- Heat of atomization- Dissociation energy-

(sum of Ionization energies)- (sum of Electron Affinities)

so lattice energy = -601.8 - 130 -498.7 - ( 738.1 + 1450) - ( 141-780)

lattice energy = - 2779.6 kJ /mol

So the lattice energy is -2779.6 kJ /mol

So the answer is C .
