how to calculate oxidaton state of ozone

Suppose the decomposition of ozone proceeds by the following mechanism:step elementary reaction rate constant1 O3(g) → O2(g) + O(g) k12 O3(g) + O(g) → 2O2(g) k2Suppose also k1≫k2. That is, the first step is much faster than the second.Write the balanced chemical equation for the overall chemical reaction: Write the experimentally-observable rate law for the overall chemical reaction. =ratek Note: your answer should not contain the concentrations of any intermediates.Express the rate constant k for the overall chemical reaction in terms of k1, k2, and (if necessary) the rate constants k-1 and k-2 for the reverse of the two elementary reactions in the mechanism. =k

One mechanism for the destruction of ozone in the upper atomosphere is:Step 1: O3 (g) + NO (g) → NO2 (g) + O2 (g) [slow]Step 2: NO2 (g) + O (g) → NO (g) + O2 (g) [fast](a) Write the balanced overall reaction with state symbols. (1 point)(b) For the uncatalysed reaction, the activation energy is 14.0 kJ. The activation energy for thesame reaction when catalysed is 11.9 kJ. What is the ratio of the rate constant for the catalysedreaction to that for the uncatalysed reaction at 25 °C? Assume that the frequency factor A is thesame for each reaction and R to be 8.314 J/mol.K. (2 points)(c) One of the concerns about the use of Freons (CCl2F2) is that they will migrate to the upperatmosphere where chlorine atoms can be generated by the following reaction:CCl2F2 (g) ℎ𝑣→ CF2Cl (g) + Cl (g)Page 2 of 3RestrictedChlorine atoms can act as a catalyst in the destruction of ozone. The activation energy for thereactionCl (g) + O3 (g) → ClO (g) + O2 (g)is 2.1 kJ. Which is the more effective catalyst (Cl or NO) for the destruction of ozone? Explain.(1 point)(d) Compare the efficiency of Cl atom and NO molecules (by calculating the ratio of 𝑘Cl𝑘NO), assumingthat the frequency factor A is the same for each reaction. Show all working.
