$O_{(g)}^{-} + e^{-} 	o O_{(g)}^{2-}$

Vedclass · Answer

(C) The process $O_{(g)}^{-} + e^{-} 	o O_{(g)}^{2-}$ involves the addition of an electron to a negatively charged ion. Due to the strong interelectronic repulsion between the incoming electron and the existing electrons in the $O^{-}$ ion,energy must be supplied to overcome this repulsion. Therefore,this process is endothermic (energy is absorbed). In contrast,the other processes involve the removal of an electron (ionization) or the addition of an electron to a positive ion,which are generally exothermic or require different energy considerations. Hence,option $C$ is the correct answer.

In which of the following processes is energy absorbed?
