Cyclopropane rearranges to form propene in the gas phase. The reaction is first order in cyclopropane and has a measured rate constant of k=3.36×10^−5 s^−1 k=3.36×10^−5 s^−1 at 720 K. If the initial cyclopropane concentration is 0.0445 MM, what will the cyclopropane concentration be after 235.0 min? Express the molarity to three significant figures.
