An unusual atmospheric reaction leading to ozone destruction is CF3O + O3 → CF3O2 + O2 The analysis of which has yielded an Arrhenius frequency factor (A) and activation energy of 2.0 × 10-12 cm3 molecule-1 s-1 and 11.6 kJ/mol, respectively. Calculate the rate constant for this reaction at an altitude of 35 km, where the temperature is -34°C.
