A following mechanism has been proposed for a reaction
`2A +B rarr D rarr E`
`A+ B rarrC+D `(slow)
`A+C rarr E` (fast)
The rate law expression for the reaction by RDS methd is:

A

`r = k[A]^(2)[B]`

B

`r = k[A][B]`

C

`r = k[A]^(2)`

D

`r = k[A][C]`

Text Solution

Verified by Experts

The correct Answer is:
B
Slow step is
`A+B rarr C+D (slow)`
Hence, `r = k[A][B]`
