    For the zeroth order reaction, sets I and II are given, hence \[x\] is
    I.
    II.

    A) 2 min                

    B)        4 min    

    C)        6 min                

    D)        8 min

    Correct Answer: C

    Solution :

    By set I, half-life is 2 min. In set-ll, number of moles have been doubled, thus half-life is also doubled, i.e., now it is 4 min. Thus, 8 mol change to 4 mol (half) in =4 min and 4 mol change to 2 mol (half) in =2 min. Thus, total time = 4 + 2 = 6 min.
