question 96

Multiple Choice

Use the data given below to construct a Born-Haber cycle to determine the lattice energy of CaO. ΔH°(kJ mol^-1)
Ca(s) → Ca(g) 193
Ca(g) → Ca⁺(g) + e⁻ 590
Ca⁺(g) → Ca²⁺(g) + e⁻ 1010
2O(g) → O₂(g) -498
O(g) + e⁻ → O⁻(g) -141
O⁻(g) + e⁻ → O²⁻(g) 878
Ca(s) + O₂(g) → CaO(s) -635
