6. The decomposition of ozone in the upper atmosphere is catalyzed by NO. The overall reaction and rate law are: O(g) + O(g) 20(8): rate-k[O][NO] Write a possible mechanism that is consistent with rate law and identify an intermediate in the reaction. 7. A possible mechanism for the iodide ion catalyzed decomposition of hydrogen peroxide in aqueous solution is: H:Os(aq) + (aq) → H2O(1) Ol(aq) --- -slow H2O2(aq) + Ol'(aq) → H2O(1) + O2(g) + l'(aq) ------fast What is: i) the overall reaction ii) the rate law iv) the intermediate iv) the catalyst? 8. Polytetrafluoroethylene) (Teflon) decomposes when heated above 500 C. Rate constants are 2,60 x 10" sat 530 C and 9.45 x 10" sat 620 C. C) what is the a) what is the rate law? b) what is rhe activation energy E, in kJ/mol? half-life of this reaction at 580 C 9. Consider the reaction: 2 NO2(g) N 04 (g) If an equilibrium mixture was found to have (NO2] -0.0125M and (N204) = 0.0337 M, what is Kc for the reaction 10. The equilibrium constant, K, for the reaction: C(s) + CO2(g) = 2co (g) is 0.113 at 1100 K. What is the concentration of CO in a mixture at equilibrium if the CO2 concentration is 0.035 M? 11. If K. = 7.5 x 10-9 at 1000 K for the reaction: N2(g) + O2(8) (a) What is Ko at 1000 K for the reaction? 2 NO(g) (b) What is Kfor the reaction N2(8) + %02(8) NO(g)
