Referring to the answer in Problem 17.21, and assuming that the level of ozone in the stratosphere has already fallen 6.0 percent, calculate the number of kilograms of ozone that would have to be manufactured on a daily basis so that we could restore the ozone to the original level in 100 years. If ozone is made according to the process 3O2(g) → 2O3(g), how many kilojoules of energy would be required?
