For the reaction , ` 2NO_2+F_5rarr 2NO_2F` following mechanism has been provided.
`NO_2+F_2overset(slow)rarrNO_2F+F`
`NO_3+Foverset("Fast")rarrNO_2+F`
Thus rate expression of the above reaction can be written as

A

`r=k[NO_(2)]^(2)[F_(2)]`

B

`r=k[NO_(2)]`

C

`r=k[[NO_(2)][F_(2)]`

D

`r=k[F_(2)]`

Text Solution

Verified by Experts

The correct Answer is:
3
Rate is given by the slowest step of the reaction so rate is `r=k[NO_(2)][F_(3)]`.
