Solved: The isolated O22 ion is unstable so it is not
Chapter 9, Problem 9.141(choose chapter or problem)
The isolated O22 ion is unstable so it is not possible to measure the electron affinity of the O2 ion directly. Show how you can calculate its value by using the lattice energy of MgO and the BornHaber cycle. [Useful information: Mg(s) S Mg(g) H 5 148 kJ/mol.]
