Elementary unimolecular reaction have first order rate laws, elementary bimolecular reaction have second order rate laws. A rate law is often derived from a proposed mechanism by imposiing the steady state approximation by assuming that there in pre equilibrium A proposal mechanism must be constat with the experimental rate law.
The decomposition of `O_(3)` obeys the mechanism given below,
Step 1: `O_(3)hArrO_(2)+(O)-` fast
Step 2: `O_(3)+(O)toO_(2)+O_(2)-` slow
Then find the incorrect one

A

Order of reaction =1

B

`r=k[O_(3)]^(2)[O_(2)]^(-1)`

C

Order with respect to `O_(3)=2`

D

Order with respect to `O_(2)=1`

Text Solution

Verified by Experts

The correct Answer is:
D
`r=K[O_(3)]^(2)[O_(2)]^(-1)`
