Identify the reaction for which $\Delta H\ne \Delta E.$

$S$ (rhombic) $+ O _{2}(g) \longrightarrow SO _{2}(g)$

$N_{2}(g)+O_{2}(g) \rightarrow 2 N O(g)$

$H _{2}(g)+ Cl _{2}(g) \rightarrow 2 HCl (g)$

$CO (g)+\frac{1}{2} O _{2}(g) \rightarrow CO _{2}(g)$

Answer

$CO (g)+\frac{1}{2} O _{2}(g) \rightarrow CO _{2}(g)$

Explanation

$\Delta H \neq \Delta E$ for $C O(g)+\frac{1}{2} O_{2}(g) \rightarrow C O_{2}(g)$ as $\Delta n \neq 0$
