Calculate the Lattice Energy for MgO(s)using a Born-Haber Cycle and the Following

question 96

Multiple Choice

Calculate the lattice energy for MgO(s) using a Born-Haber cycle and the following information: MgO(s) → Mg²⁺(g) + O^2-(g) ?
Mg(s) → Mg(g) +147.1 kJ/mol
Mg(g) → Mg⁺(g) + e^- +737.8 kJ/mol
Mg⁺(g) → Mg²⁺(g) + e^- +1451 kJ/mol
1/2 O₂(g) → O(g) +249.0 kJ/mol
O(g) + e^- → O^-(g) -141.1 kJ/mol
O^-(g) + e^- → O^2-(g) +798.0 kJ/mol
Mg(s) + 1/2 O₂(g) → MgO(s) -601.8 kJ/mol

• A)+1842 kJ/mol
• B)+2444 kJ/mol
• C)+3844 kJ/mol
• D)+4108 kJ/mol
