The electron affinity of oxygen is -141kj/mol, corresponding to the reaction 

O(g)+e-—>O-(g)

The lattice energy of K2O(s) is 2238kj/mol.Use these data along with data in Appendix C and figure 7.10 to calculate the “second electron affinity” of oxygen, corresponding to the reaction 

O-(g)+e-—>O2-(g)
