Chlorine monoxide (ClO) plays a major role in the creation of the ozone holes in the stratosphere over Earth's polar regions.

1. If at 298 K is -22.93x10^-6 M/s, what is the rate of change in [Cl2] in the following reaction?

2ClO(g) = Cl2(g) + O2(g)

2. What is the rate of change in [O2] in the reaction?

3. If is -28.21x10^-3 M/s, what is the rate of appearance of oxygen in the following reaction?

ClO(g) + O3(g) = O2(g) + ClO2(g)

4. What is the rate of appearance of ClO2?
