The process that is NOT endothermic in nature is :

Answer:

Solution:

$H_{(g)} {+e}^{-} \overset{extremic}{\to} {H^{-}}_{(g)}$	${ΔH}_{eg} = - 72 KJ / mol$
$O^{-} (g) + e^{-} ⟶ \overset{endeterm c}{\to} O^{2 -} (g)$	${ΔH}_{eg} = + 744 KJ / mol$
${Ar}_{(g)} + e^{-} \overset{endeterm c}{\to} {Ar}^{-} (g)$	${ΔH}_{eg} = + 96 KJ / mol$
$Na (g) \overset{endotherm c}{⟶} {Na}^{+} (g) + e^{-}$	$IE = 495.8 KJ / mol$
