Vedclass · Answer

(C) The second electron gain enthalpy is the energy change when an electron is added to a uninegative ion $(X^-)$.For oxygen $(O)$ and sulphur $(S)$,the addition of the second electron is an endothermic process due to strong inter-electronic repulsion between the incoming electron and the negative ion.The values for the $2^{nd}$ electron gain enthalpy of $O$ and $S$ are $+ 780 \ kJ/mol$ and $+ 590 \ kJ/mol$ respectively.Therefore,the correct option is $C$.

The value of $2^{nd}$ electron gain enthalpy for $O$ and $S$ will be (in $kJ/mol$)
