Question

The depletion of ozone involves the following steps:

Step 1: O3 --> O2 + O (fast)
Step 2: O3 + O ----> 2O2 (slow)

The predicted order of the reaction will be?​

Answer 2

Answer: 1

Explanation: As we know the slowest step is the RDS(Rate Determining Step)

So in the mentioned question, the RDS is the Step 2.

So for step 2 , Rate= k [O3] [O]

As 'O' is intermediate, so the concentration of O ie. [O] is negligible,

So the Rate =k [O3]

Which is of 1st order
