Question

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. You must have the correct sig figs. 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 x 10^-5 mol/Ls. What is the rate of appearance of O3?

Answer 1

-d[O2]/dt

d[O3]/dt= d[O2]/dt=1.61*10^-5molL-1

Step-by-step explanation:

The rate if disappearance of reactant is the same as the rate at which it is converted to product or the rate at which the product appears. Hence the solution. This is because the reactant is directly converted to product.
