The following mechanism has been proposed for the reaction of NO with `Br_(2)` to from NOBr.
`NO(g)+Br_(2)hArrNOBr_(2)(g)`
`NOBr_(2)(g)+NO(g)rarr2NOBr(g)`
If the second step is the rate determining step, the order of the reaction with respect to NO(g) is

A

Text Solution

Verified by Experts

The correct Answer is:
D
`NO(g) +Br_(2) (g) , NOBr_(2)(g) rArr NOBr_(2) (g) + NO (g) rarr 2NOBr (g)`
`R =k [NOBr_(2)] [NO] =k K_(c ) [NO] [Br_(2)] [NO]," where "K_(c ) =([NOBr_(2)])/([NO][Br_(2)])=k' [NO]^(2) [Br_(2)]`
