    The degree of dissociation of A is a in equilibrium reaction,\[A2B+C\]. If initially one mole of A is taken then the total number of moles at equilibrium will be

    A)  \[1-\alpha \]            

    B)  \[1+\alpha \]

    C)  \[1-2\alpha \]           

    D)  \[1+2\alpha \]

    Correct Answer: D

    Solution :

     \[A2B+C\]
    1 0 0 in initial
    \[1-\alpha \] \[2\alpha \] \[\alpha \] at eqm.
    Total number of moles\[=1-\alpha +2\alpha +\alpha \] \[=1+2\alpha \]
