Mechanism of the reaction 2NO + Cl(2) ra...

Mechanism of the reaction `2NO + Cl_(2) rarr 2NOCl` may be written as
`2NO overset(k)(hArr) (NO)_(2)`……….(fast)
`(NO)_(2) + Cl_(2) overset(k)rarr 2NOCl`……….(slow)
Rate equation would be

A

`kK[(NO)_(2)][Cl_(2)]`

B

`kK[(NO)^(2)][Cl_(2)]`

C

`kK[Cl_(2)]`

D

`kK[NO][Cl_(2)]`

Text Solution

Verified by Experts

The correct Answer is:
B
`r = K[NO]_(2)[Cl_(2)]`
`K' = ([NO]_(2))/([NO]^(2))`
`r = KK' [NO]^(2)[Cl_(2)]`
