Answer:
it increases from left to right in a period.
oxygen has more negative electron gain enthalpy due to it's small size, high electron density and inter electronic repulsion between the existing electrons and the incoming electrons.

Answer:
S has high electron gain enthalpy because in sulphur there is more inter-electronic repulsion than oxygen, therefore, more energy is released in case of sulphur on gaining electrons.
