🤓 Based on our data, we think this question is relevant for Professor Harika's class at GSU.
The lattice enthalpy of calcium oxide is the energy change for the reaction
1. CaO(s) → Ca(g) + ½ O2(g)
2. Ca(g) + ½ O2(g) → CaO(s)
3. Ca(g) + O(g) → CaO(g)
4. CaO(s) → Ca2+(g) + O2- (g)
5. CaO(s) → Ca(g) + O(g)
