The decomposition of cyclopropane to propene is a unimolecular reaction. It can be studied over a range of pressures. The following data gives values of over a range of concentrations. Plot kos versus concentration and comment on the shape of the graph. Note: PV = nRT, hence pressure is proportional to concentration. 104c 0.120 0.605 1.27 2.31 7.13 159 mol dm7 obs 10k 1st 8-1 8.6 15.4 20.0 22.3 28.2 38.7 Problem 3. (a) From the data in problem 2 find [A]1/2 and show this to equal k/k_1. (b) Find k and then k, taking Z = 5 10 mol- dm s, and X = 1. (c) Why can k_ be taken to equal a typical value of Z, the collision number
