Here they provide a proposed mechanism for the decomposition of ozone.
00:07
The first step is ozone, separating into o2 and o, and they tell us that the first step is much slower than the second, so this is the slow or rate determining step.
00:27
The second step then is o3, taking on o to become two.
00:35
O2 gas.
00:38
So the overall balanced reaction will be the sum of these two, where we see o is an intermediate being canceled, and we get 2, 03, going to 3, 02.
00:56
The experimentally observable rate law for the overall chemical equation would come from the rate law for the rate determining step, the slow step, and that, that.
01:11
That is written according to the molecularity of the reaction rate is equal to k multiplied by we only have ozone as a product and just one of them.
01:23
So this is the rate law for the first step and if it's the slow step which they tell us it is then it's also the rate determining step and this is the rate law for the overall reaction...
