The following initial rate data are for the reaction of nitrogen dioxide with carbon monoxide:
\[
\mathrm{NO}_{2}+\mathrm{CO} \rightarrow \mathrm{NO}+\mathrm{CO}_{2}
\]
\begin{tabular}{|l|l|l|l|}
\hline Experiment & {\( \left[\mathrm{NO}_{2}\right]_{0}, \mathrm{M} \)} & {\( [\mathrm{CO}]_{0}, \mathrm{M} \)} & Initial Rate, \( \mathrm{M} \cdot \mathrm{s}^{-1} \) \\
\hline 1 & 1.35 & 0.161 & 1.04 \\
\hline 2 & 1.35 & 0.322 & 1.04 \\
\hline 3 & 2.70 & 0.161 & 4.16 \\
\hline 4 & 2.70 & 0.322 & 4.16 \\
