Second electron gain enthalpy is always positive because after first e -ion will have negative charge shows repulsion towards new electron.

Q. Which of the following processes involves absorption of energy?

$Cl (g) + e^{-} ⟶ C l^{-} (g)$

$O^{-} (g) + e^{-} ⟶ O^{2 -} (g)$

$O (g) + e^{-} ⟶ O^{-} (g)$

$S (g) + e^{-} ⟶ S^{-} (g)$

Second electron gain enthalpy is always positive because after first $e^{-}$ ion will have negative charge shows repulsion towards new electron.

Q. Which of the following processes involves absorption of energy?

Cl(g)+e−⟶Cl−(g)

O−(g)+e−⟶O2−(g)

O(g)+e−⟶O−(g)

S(g)+e−⟶S−(g)
