In the stratosphere, the rate constant for the conversion of ozone to molecular oxygen by atomic chlorine is

a. What is the rate of this reaction at 20 km where

b. The actual concentrations at 45 km are [Cl] = 3 × 10^ˆ’15 M and [O₃] = 8 × 10^-11 M. What is the rate of the reaction at this altitude where T = 270. K?

c. (Optional) Given the concentrations in part (a), what would you expect the concentrations at 45 km to be assuming that the gravity represents the operative force defining the potential energy?
