To determine the kinetics (rates) of ozone depletion reactions, chemists perform controlled laboratory studies. In this simulated lab, we will interpret data obtained from such laboratory experiments to study the ozone depletion reaction:
O3 (g)+ O(g) 2O2(g) (1)
The results from 12 experiments are shown below

- (4 pts) Experiments 1 through 4 are done in the absence of chlorine. This information can be used to determine the rate law of the uncatalyzed reaction. Once you have determined your rate law, add two columns to the above data: one that predicts the rate of the reaction based on your rate law, and one that shows the % error between your prediction and the experimentally observed rate. (Throughout this activity, your rate law should reproduce the experimental rates to better than 5%).
