Solution

The correct option is B $5 t h$ order overall
For a reaction, $r a t e = k [A]^{x} [B]^{y} [C]^{z}$ , the overall rate of reaction is given as
$o r d e r = x + y + z$
Therefore, for the given reaction,
Order can be given by 2 (for A)+3 (for B) = 5

R a t e = k [A]^{2} B

\frac{d x}{d t} = K [A]^{\frac{1}{2}} [B]^{\frac{3}{2}}

\frac{d x}{d t} = k {[A]}^{1 / 2} {[B]}^{3 / 2}
