Question

The process that is NOT endothermic in nature is :- (A) Ar ( g )+ e - arrow Ar ( g ) - (B) H ( g )+ e - arrow H ( g ) - (C) Na ( g ) arrow Na g ++ e - (D) O ( g )-+ e - arrow O ( g ) 2-

H ( g )+ e - arrow H - is exothermic rest of all endothermic process.

Q. The process that is $NOT$ endothermic in nature is :-

$A r_{(g)} + e^{-} \to A r_{(g)}^{-}$

$H_{(g)} + e^{-} \to H_{(g)}^{-}$

$N a_{(g)} \to N a_{g}^{+} + e^{-}$

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

$H_{(g)} + e^{-} \to H^{-}$ is exothermic rest of all endothermic process.

Q. The process that is NOT endothermic in nature is :-

Ar(g)​+e−→Ar(g)−​

H(g)​+e−→H(g)−​

Na(g)​→Nag+​+e−

O(g)−​+e−→O(g)2−​
