Use the Data Given Below to Construct a Born-Haber Cycle

Question 83

Multiple Choice

Use the data given below to construct a Born-Haber cycle to determine the second ionization energy of Ca. ΔH°(kJ mol-1)
Ca(s) → Ca(g) 193
Ca(g) → Ca⁺(g) + e⁻ 590.
2O(g) → O2(g) -498
O(g) + e⁻ → O⁻(g) -141
O⁻(g) + e⁻ → O2⁻(g) 878
Ca(s) + Use the data given below to construct a Born-Haber cycle to determine the second ionization energy of Ca. ΔH°(kJ mol<sup>-1</sup>) Ca(s) → Ca(g) 193 Ca(g) → Ca⁺(g) + e⁻ 590. 2O(g) → O<sub>2</sub>(g) -498 O(g) + e⁻ → O⁻(g) -141 O⁻(g) + e⁻ → O<sup>2</sup>⁻(g) 878 Ca(s) + O<sub>2</sub>(g) → CaO(s) -635 Ca<sup>2</sup>⁺(g) + O<sup>2</sup>⁻(g) → CaO(s) -3414 A) 1010 kJ B) 1757 kJ C) 1508 kJ D) -3027 kJ E) -1514 kJ O2(g) → CaO(s) -635
