The formation of the oxide i on O2-(g) requires first an exothermic and then an endothermic step as shown below  
O(g) + e- = O-(g) ΔHº =-142 kJmol-1                [2004]
 O-(g) + e- = O2-(g) ΔHº= 844 kJmol-1 
This  is because
  • a)
    O ion will ten d to r esist th e addition of another electron
  • b)
    Oxygen has high electron affinity
  • c)
    Oxygen is more elecronegative
  • d)
    O ion has comparatively larger size than oxygen atom
Correct answer is option 'A'. Can you explain this answer?
