The decomposition of ozone may occur through the two-step mechanism shown below:
step 1 O3 ----> O2 + O
step 2 O3 + O ---> 2O2
The oxygen atom is considered to be: a catalyst or reaction intermediate?
How am I supposed to be able to tell the difference between the two? I know a catalyst speeds up a reaction without be consumed, but I'm not sure on how to be able to identify a reaction intermediate.
