The initial rates of decrease of $I_2$ in acetone-iodine reaction catalysed by $H^{+}$ are given in the table.
ExperimentInitial $[I_2]$ $(mol \ L^{-1})$Initial $[H^{+}]$ $(mol \ L^{-1})$Initial $[CH_3COCH_3]$ $(mol \ L^{-1})$Initial rate $(mol \ L^{-1} \ s^{-1})$
$1$$0.01$$0.1$$0.1$$0.096$
$2$$0.01$$0.2$$0.1$$0.192$
$3$$0.02$$0.2$$0.1$$0.192$
$4$$0.01$$0.2$$0.2$$0.384$

The order with respect to $I_2, H^{+}$,acetone and total order of the reaction respectively are:

  • A
    $0, 2, 1, 3$
  • B
    $1, 0, 1, 2$
  • C
    $0, 1, 1, 2$
  • D
    $1, 1, 0, 2$
