The decomposition of ozone in the upper atmosphere to dioxygen occurs by a two-step mechanism.The first step is a fast reversibl
alex41 [277]

<u>Answer:</u> Step 2 in the given mechanism is the rate determining step

<u>Explanation:</u>

In a mechanism of the reaction, the slow step in the mechanism determines the rate of the reaction.

The intermediate reaction of the mechanism follows:

<u>Step 1:</u>  O_3(g)\rightleftharpoons O_2(g)+O(g);\text{ (fast)}

<u>Step 2:</u>  O_3(g)+O(g)\rightarrow 2O_2(g);\text{(slow)}

As, step 2 is the slow step. It is the rate determining step

Rate law for the reaction follows:

\text{Rate}=k[O_3][O]

Hence, step 2 in the given mechanism is the rate determining step
