The experimental unimolecular first-order rate constant, kuni, for the isomerisation of cyclopropane to propene at 743K versus the initial pressure, P0, are as follows: The following mechanism was proposed for the above unimolecular isomerisation of cyclopropane to propene: A+Ak11A+AAk2Y+Z The species A is an energised molecule that is present in low concentration. Show that the mechanism predicts first-order kinetics at high pressure limit and secondorder kinetics at low pressure limit. From the data given, determine the first-order rate constant, k, at high pressures and the Lindermann parameters k1 and (k1/k2)
