    \[\Delta n\], the change in the number of moles for the reaction, \[{{C}_{12}}{{H}_{22}}{{O}_{11}}_{(s)}\]\[+12{{O}_{2(g)}}\] ⇌ \[12C{{O}_{2(g)}}\] \[+11{{H}_{2}}{{O}_{(l)}}\] at 25°C is                                              [Pb. PMT 2002]

    A)                 0             

    B)                 2

    C)                 4             

    D)                 ? 1

    Correct Answer: A

    Solution :

               \[{{C}_{12}}{{H}_{22}}{{O}_{11(s)}}+12{{O}_{2(g)}}\to 12C{{O}_{2(g)}}+11{{H}_{2}}O\]                                 \[\Delta n=12-12=0\]
