KClO3 decomposes according to the reaction:
2KClO3 → 2KCl + 3O2
If the rate of decomposition of potassium chlorate at a certain time is determined to be 2.4 x 10-2 mol s-1. What is the rate of formation of O2 at the same time?

From balanced equation we have
2 X rate of decomposition of KClO3 = 3 X rate of formation of O2
You plug in the values and solve it for rate of formation of O2 .
After calculations you will get this answer.
3.6 x 10-2 mol s-1
