A reaction `A_(2)+B_(2)to2AB` occurs by the following mechanism:
`A_(2)hArr A+A`…………(fast)
`A+B_(2)toAB+B`……….(slow)
`A+BtoAB`…………..(fast) Its order would be:

A

44257

B

1

C

zero

D

2

Text Solution

Verified by Experts

The correct Answer is:
A
`r=K_(1)(A)[B_(2)],r=K_(1)(K_(c))^(1/2).[A_(2)]^(1/2)[B_(2)]^(1)[r]=K.[A_(2)]^(1/2)[B_(2)]`
order `=1/2+1=3/2,K_(C)=([A]^(2))/([A_(2)]),[A]=(K_(c))^(1/2).[A_(2)]^(1/2)`
