$(ii)$ $CH _{3} COOH$
$(iii) $ $C _{6} H _{5} COOH$
$(iv)$ $CH _{3} CH _{2} COOH$
Correct order of $pK _{ a }$ value is :
$X + \frac{1}{2}{O_2}\,\, \to \,\,XO + 90.8\,kJ$
It follows that the heat of reaction for the following process $M + XO$ $\rightleftharpoons$ $MO + X$ is given by......$kJ$
${{O}_{(g)}}+{{e}^{-}}=O_{(g)}^{-}\Delta {{H}^{o}}=-142\ kJ\,mo{{l}^{-1}}$
$O_{(g)}^{-}+{{e}^{-}}=O_{(g)}^{2-}\Delta {{H}^{o}}=844\ kJ\,mo{{l}^{-1}}$
