When the first electron gain enthalpy `(triangle_(eg)H)` of oxygen is `-141 kJ//mol,` its second electron gain enthalpy is :

Electron gain enthalpy values

The second electron gain enthalpy of oxygen is

Electron gain enthalpy is known as

The formation of O^(2-)(g) startng from O(g) is endothermic by 603 kJ mol^(-1) . If electron gain enthalpy of O(g) is -141 kJ mol^(-1) , the second electron gain enthalpy of oxygen would be :

Electron gain enthalpy is positive when:

The formation of \(O^{2-}\) from \(O_{(g)}\) is endothermic by \(639kJmol^{-1}\) .If electron gain enthalpy of \(O_{(g)}\) is \(-141kJmol^{-1}\) the second electron gain enthalpy of oxygen would be.

The correct order of electron gain enthalpy (in kJ/mole) is
