Derive the rate law for the decomposition of ozone in the reaction 2 O3(g)→3 O2(g) on the basis of the (incomplete) mechanism: O3→O2 + O ka O2 + O→O3 k′a O + O3→O2 + O2 kb This reaction presents two limit behaviours: a) it is of first order with respect to O3 concentration b) it is of second order with respect of the O3 concentration. Under which conditions do you think you will get one or the other? Assume you can use the stationary state approximation. Which will be the half-life time of the ozone if behaviour a) is assumed?
