The reaction between X and Y is first order with respect to X and zero order with respect to Y.

Experiment	$\frac{[X]}{m o l L^{- 1}}$	$\frac{[Y]}{m o l L^{- 1}}$	$\frac{I n i t i a l r a t e}{m o l L^{- 1} {min}^{- 1}}$
I	0.1	0.1	$2 \times 10^{- 3}$
I	L	0.2	$4 \times 10^{- 3}$
III	0.4	0.4	$M \times 10^{- 3}$
IV	0.1	0.2	$2 \times 10^{- 3}$

Examine the data of table and calculate ratio of numerical values of M and L. (Nearest Integer)

Accepted Answer

r = k [X] [Y]^{0} = k [X]

Using I & II

\frac{4 \times 10^{-3}}{2 \times 10^{-3}}=\left(\frac{L}{0.1}\right) \quad \Rightarrow \quad \mathrm{L}=0.2

Using I & III

\frac{M \times 10^{-3}}{2 \times 10^{-3}}=\frac{0.4}{0.1} \quad \Rightarrow \quad \mathrm{M}=8

\frac{M}{L}=\frac{8}{0.2}=40
