If the rate law of a reaction $n A \rightarrow B$ is expressed as Rate $= -\frac{1}{n} \frac{d[A]}{dt} = \frac{d[B]}{dt} = k[A]^{x}$,the unit of rate constant $k$ will be:

  • A
    $mol^{1-x} \ L^{x-1} \ sec^{-1}$
  • B
    $L^{x-1} \ mol^{1-x} \ sec^{-1}$
  • C
    $mol^{x-1} \ L^{1-x} \ sec^{-1}$
  • D
    $L^{x} \ mol^{-x} \ sec^{-1}$
