    What is \[\Delta n\] for combustion of 1 mole of benzene, when both the reactants and the products are gas at 298 K [Pb. PMT 2001]

    A)                 0             

    B)                 3/2

    C)                 ? 3/2     

    D)                 ½

    Correct Answer: D

    Solution :

           \[{{C}_{6}}{{H}_{6(g)}}+\frac{15}{2}{{O}_{2(g)}}\to 6C{{O}_{2(g)}}+3{{H}_{2}}{{O}_{(g)}}\]                                 \[\Delta n=6+3-1-\frac{15}{2}=+\frac{1}{2}\].
