Question

A chemistry graduate student is studying the rate of this reaction: 2SO$_3$(g) \rightarrow 2SO$_2$(g) + O$_2$(g) She fills a reaction vessel with SO$_3$ and measures its concentration as the reaction proceeds: \begin{tabular}{|c|c|} \hline time \\ (minutes) & [SO$_3$] \\ \hline 0 & 0.0700M \\ 10. & 0.0349M \\ 20. & 0.0174M \\ 30. & 0.00870M \\ 40. & 0.00434M \\ \hline \end{tabular} Use this data to answer the following questions. Write the rate law for this reaction. rate = $k$ Calculate the value of the rate constant $k$. Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol.
