The electron gain enthalpy values for O → O– and O → O2– are –141 and 702 kJ mol-1 , respectively. The correct statement about the formation of oxides is-
1. | Higher the electron gain enthalpy lower is the lattice energy. |
2. | Higher the electron gain enthalpy higher is the lattice energy. |
3. | Higher the electron gain enthalpy higher is the stability of oxide. |
4. | O- is more stable than O2- |
