Vedclass · Answer

(B) The process of adding an electron to a neutral atom (first electron gain enthalpy) is generally exothermic,meaning energy is released. However,adding an electron to an already negatively charged ion (like $S^-$) requires overcoming the electrostatic repulsion between the incoming electron and the negative ion. Therefore,energy must be supplied (absorbed) to force the second electron onto the anion. In the reaction $S^{-}_{(g)} + e^- 	o S^{2-}_{(g)}$,energy is absorbed.

Which of the following processes involves absorption of energy?
