Hydrogen iodide can be synthesized from the elements in a gas-phase reactions. One proposed mechanism for the process is ?2 → 2? (?1, ???? ????????) 2? → ?2 (?2) ?2 + 2? → 2?? (?3)  Derive the differential rate law for the rate of production of HI and identify the order for each species and the overall order if ?2 and ? are in equilibrium. Derive the differential rate law for the rate of production of HI if a stationary state approximation can be applied to ? atoms with ?3[?2] ≫ ?2. Which of these assumption is correct?
