During Kinetic study of reaction $\mathrm{2 A+B \rightarrow C+D}$ , the following results were obtained :

	$\mathrm{A [M]}$	$\mathrm{B [M]}$	initial rate of formation of $\mathrm{D}$
I	0.1	0.1	$6.0\times10^{-3}$
II	0.3	0.2	$7.2\times10^{-2}$
III	0.3	0.4	$2.88\times10^{-1}$
IV	0.4	0.1	$2.40\times10^{-2}$

Based on above data, overall order of the reaction is _________.

Correct Answer:

\begin{aligned} & \text { Rate }=k[A]^x[B]^y \\ & \frac{6 \times 10^{-}}{2.4 \times 10^{-}}=\left(\frac{0.1}{0.4}\right)^x \Rightarrow x=1 \\ & \frac{7.2 \times 10^{-}}{2.88 \times 10^{-}}=\left(\frac{0.2}{0.4}\right)^y \Rightarrow y=2 \end{aligned}
