    Identify the reaction for which\[\Delta H\ne \Delta E\].

    A) \[S(\text{rhombic})+{{O}_{2}}(g)\xrightarrow{{}}S{{O}_{2}}(g)\]

    B) \[{{N}_{2}}(g)+{{O}_{2}}(g)\xrightarrow{{}}2NO(g)\]

    C)  \[{{H}_{2}}(g)+C{{l}_{2}}(g)\xrightarrow{{}}2HCl(g)\]

    D) \[CO(g)+\frac{1}{2}{{O}_{2}}(g)\xrightarrow{{}}C{{O}_{2}}(g)\]

    Correct Answer: D

    Solution :

    \[\Delta H\ne \Delta E\]for\[CO(g)+\frac{1}{2}{{O}_{2}}(g)\xrightarrow{{}}C{{O}_{2}}(g)\]as\[\Delta n\ne 0\].
