In the sequence of reaction,
`L overset(k_(1))rarr M overset(k_(2))rarr N overset(k_(3))rarrO`
`k_(3) gt k_(2) gt k_(1)`
The rate determining step of the reaction is :

A

`ArarrB`

B

`BrarrC`

C

`CrarrD`

D

`ArarrD`

Text Solution

Verified by Experts

The correct Answer is:
A
`Aoverset(k_(1))rarrBoverset(K_(2))rarrCoverset(k_(3))rarrD`
`because" "k_(3)gtk_(2)gtk_(1)`
As `k_(1)` is slowest, hence `ArarrB` is the rate of determining step of the reaction.
