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

The following mechanism has been propsoed for the reaction of NO with Br_(2) to form NOBr. NO(g) +Br_(2)(g) hArr NOBr_(2)(g), NOBr_(2)(g) +NO(g) rarr 2NOBr(g)" " (slow step) If the second step is the rate determining step, the order of the reaction with respect to NO(g) is:

The following mechanism has been proposed for the reaction of NO and Br_2 to form NOBr NO (g) + Br_2(g) harr NOBr_2 (g) (fast) NOBr_2 (g) + NO harr 2NOBr(g) (slow) If the second step is rate determining step, the order of the reaction with respect to NO(g) is

The following mechanism has been proposed for the reaction of (NO) with (Br)_(2) to form NOBr . (NO)(g)+(Br)_(2)(g) harr (NOBr)_(2)(g). NOBr2 (g) + NO (g) = 2NOBr (g) . If the 2nd step is the rate determining step , the order of the reaction with respect to (NO)(g) is
