In a study of the rearrangement of cyclopropane to propene at 500 °C (CH2)3 CH3CH=CH₂ the concentration of (CH₂)3 was followed as a function of time. It was found that a graph of In[(CH₂)3] versus time in seconds gave a straight line with a slope of -9.38×104 s¹¹ and a y-intercept of -2.02. Based on this plot, the reaction is order in (CH₂)3 and the rate constant for the reaction is
