Question

A following mechanism has been proposed for a reaction:
`2A+Brarr D+E`
`A+B rarr C+D` (slow)
`A+C rarr E` (fast)
The rate law expresison for the reaction is
A. `r = k[A]^(2)[B]`
B. `r = k[A][B]`
C. `r = k[A]^(2)`
D. `r = k[A][C]`

Answer 1

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

Answer 2

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