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

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

    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 \[\Delta n\ne 0\]
