    The given graph is a representation of kinetics of a reaction. image The `` y `` and `` x `` axes for zero and first order reactions, respectively are
    (A)zero order ( `` y= `` rate and `` x= `` concentration), first order `` \left(y=\right. `` rate and `` \left.x= t _{1 / 2}\right) ``
    (B)zero order ( `` y= `` concentration and `` x= `` time), first order ( `` y= t _{1 / 2} `` and `` x= `` concentration)

    (C)zero order ( `` y= `` concentration and `` x= `` time), first order `` (y= `` rate constant and `` x= `` concentration)
    (D)zero order ( `` y= `` rate and `` x= `` concentration), first order `` \left(y= t _{1 / 2}\right. `` and `` x= `` concenration `` ) ``

    Ans : image
    (I) curve is suitable for zero order if `` y= `` rate and `` x = `` concentration because in case of zero order reaction rate is constant and does not depend on conc `` ^{ n } `` .
    (II) curve is suitable for first order if `` y=t_{1 / 2} `` and `` x= `` conc `` ^{n} `` because in case of first order `` t_{1 / 2} `` does not depend on conc `` ^{ n } `` .
