$A \rightarrow$ products, is a first order reaction. The following data is obtained for this reaction at $T(\mathrm{~K})$. The value of $x: y$ is

$$ \begin{array}{cc} \hline \text { Rate }\left(\mathrm{molL}^{-1} \mathrm{~min}^{-1}\right) & {[A]} \\ \hline 0.2 & 0.02 \mathrm{M} \\ \hline 0.4 & x \mathrm{M} \\ \hline 1.0 & y \mathrm{M} \\ \hline \end{array} $$
