The reaction `2A+Bto` product follow the mechanism :-
`2AhArrA_(2)("fast")`
`A_(2)+BtoP(slow)`
`The order of the reaction is

A

2

B

1

C

3

D

`1(1/2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`r=K[A_(2)][B]`…….(i)
`K=[A_(2)]/[A]^(2)`
`therefore [A_(2)] = K[A]^(2)`….(ii)
From (i) and (ii)
`r=KK[A]^(2)[B] = K.[A]^(2)[B]`
