    If, in the reaction \[{{N}_{2}}{{O}_{4}}2N{{O}_{2}},\,\,x\] is that part of \[{{N}_{2}}{{O}_{4}}\] which dissociates, then the number of molecules at equilibrium will be :

    A)  1                                            

    B)  3

    C)  \[(1+x)\]                            

    D)  \[{{(1+x)}^{2}}\]

    Correct Answer: C

    Solution :

    \[{{N}_{2}}{{O}_{4}}\,\,\,\,\,\,\,\,\,2N{{O}_{2}}\] 1                              0     before dissociation \[1-x\]                  \[2x\] after dissociation Total number of moles at equilibrium                                                 \[=1-x+2x=1+x\]
