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 -9.11×104 s¹ and a y-intercept of -1.58. Based on this plot, the reaction is ✓order in (CH₂)3 and the half life for the reaction is seconds.
