  • question_answer
    At constant T and P, which one of the following statements is correct for the reaction, \[CO(g)+\frac{1}{2}{{O}_{2}}(g)\to C{{O}_{2}}(g)\]

    A) \[\Delta H\] is independent of the physical state of the reactants of that compound

    B) \[\Delta H\,>\,\Delta E\]

    C) \[\Delta H\,<\,\Delta E\]

    D) \[\Delta H=\Delta E\]

    Correct Answer: C

    Solution :

    [c] \[\Delta {{n}_{g}}=1-\frac{3}{2}=\frac{-1}{2}\], As \[\Delta {{n}_{g}}\]is negative, thus \[\Delta H<\Delta E\].
