Just as the depletion of stratospheric ozone today threatens life on Earth today, its accumulation was one of the crucial processes that allowed life to develop in prehistoric times.
3 O2 (g) ---> 2 O3 (g)
a. Express the rate of reaction in terms of the rate of disappearance of O2 and the rate of appearance of O3.
b. At a given instant, the rate of disappearance of O2 is 1.61 x10^-5 mol/Ls. What is the rate of appearance of O3?
