Oxygen has less electron gain enthalpy with negative sign than sulphur

1.	Oxygen has less electron gain enthalpy with negative sign than sulphur, why?
Answer» Electron gain enthalpy of oxygen = -141 kJ /mol Electron gain enthalpy of S = -200 kJ /mol Thus electron gain enthalpy of S is more than O. This is due to greater inter electronic repulsion in O than S which results owing to smaller size of O than S.

Answer»

Electron gain enthalpy of oxygen = -141 kJ /mol

Electron gain enthalpy of S = -200 kJ /mol

Thus electron gain enthalpy of S is more than O. This is due to greater inter electronic repulsion in O than S which results owing to smaller size of O than S.
