For the reaction $X_{2(g)} + Y_{2(g)} \rightarrow 2XY_{(g)}$,the following data are observed:
$[X_{2}] \ (M)$ $[Y_{2}] \ (M)$ Rate of appearance of $XY \ (M \ sec^{-1})$
$0.1$ $0.1$ $5 \times 10^{-6}$
$0.2$ $0.1$ $10^{-5}$
$0.2$ $0.2$ $4 \times 10^{-5}$

Calculate the rate constant of the reaction (in $M^{1-n} \ sec^{-1}$),where $n$ is the order of the reaction.
