The correct options for the rate law that corresponds to overall first order reaction is
A
Rate = $k[A]^0[B]^2$
B
Rate = $k[A][B]$
C
Rate = $k[A]^{1/2}[B]^2$
D
Rate = $k[A]^{-1/2}[B]^{3/2}$
Detailed Solution
Overall order = sum of the individual orders. For $r=k[A]^{-1/2}[B]^{3/2}$: order $=-\dfrac{1}{2}+\dfrac{3}{2}=\dfrac{2}{2}=1$, i.e. overall first order.
