The thermal decomposition of ozone in the gas phase is thought to proceed via the reactive intermediate, oxygen atom; overall: 2 O_3 --> 3 O_2. Mechanism:  O_3 --> O_2 + O         k_1 O + O_2 --> O_3         k_2 O + O_3 --> 2 O_2      k_3 Apply the steady-state approximation and obtain an expression for the rate of loss of ozone, d[O_3]/dt. You may assume that [O_2] is large and unchanging.  (show all work)
