    For the reaction \[{{C}_{3}}{{H}_{8}}(g)\,\,+\,\,5{{O}_{2}}(g)\,\,\to 3C{{O}_{2}}(g)\,\,+\,\,4{{H}_{\text{2}}}\text{O(}\ell \text{)}\] at constant temperature, \[\Delta H\,\,-\,\,\Delta U\] is-

    A) \[-RT\]              

    B) \[RT\]

    C) \[-3RT\]            

    D) \[+3RT\]

    Correct Answer: C

    Solution :
