Hello, i need help with these questions. Please provide a handwritten solution for better understanding. One pathway for the destruction of ozone in the upper atmosphere is O3(g) + NO(g)---> NO2(g) + O2(g) Slow NO2(g) + O(g) ---> NO(g) + O2(g) Fast Overall reaction: O3(g) + O(g)---> 2O2(g) Ea is 14.0 kJ/mol, for the uncatalyzed reaction: O3(g) + O(g) --> 2O2(g) 1a) Ea for the same reaction, when catalyzed as above, is 11.9 kJ/mol.At -37°C, what is the ratio of the rate constant for the catalyzed reaction to that for the uncatalyzed reaction?(Assume the frequency factor A is the same for each reaction.) 1b) One of the concerns about the use of freons is that they will migrate to the upper atmosphere, where chlorine atoms can be generated by the reaction CCl2F2 CF2Cl + Cl (photolysis of Freon-12) Chlorine atoms can also act as a catalyst for the destruction of ozone.The activation energy for the reaction Cl + O3 --> ClO + O2 is 2.1…
