The correct option for the rate law that corresponds to overall first order reaction is

Options

  1. ARate =k[A]1/2[B]2=k[A]^{1 / 2}[B]^2
  2. BRate =k[A]−1/2[ B]3/2=k[A]^{-1 / 2}[\mathrm{~B}]^{3 / 2}
  3. CRate =k[A]0[ B]2=k[A]^0[\mathrm{~B}]^2
  4. DRate =k[A][B]=k[A][B]

Correct answer

B. Rate =k[A]−1/2[ B]3/2=k[A]^{-1 / 2}[\mathrm{~B}]^{3 / 2}

Step-by-step solution

Rate =k[A]−12[B]32=k[A]^{-\frac{1}{2}}[B]^{\frac{3}{2}} So, order of reaction =−12+32=1=-\frac{1}{2}+\frac{3}{2}=1
