Question
The following mechanism has been proposed for the reaction of NO with Br2 to form NOBr:
NO(g) + Br2(g) ⇋ NOBr2(g)
NOBr2(g) + NO(g) → 2NOBr(g)
If the second step is the rate determining step, the order of the reaction with respect to NO(g) is
NO(g) + Br2(g) ⇋ NOBr2(g)
NOBr2(g) + NO(g) → 2NOBr(g)
If the second step is the rate determining step, the order of the reaction with respect to NO(g) is
Options
A.1
B.0
C.3
D.2
Solution
NO(g) + Br2(g) ⇋ NOBr2(g)
NOBr2(g) + NO(g) → 2NOBr(g)
R = K[NOBr2] [NO]
= K. K [NO][Br2][NO], where Kc =
= K′[NO]2 [Br2]
NOBr2(g) + NO(g) → 2NOBr(g)
R = K[NOBr2] [NO]
= K. K [NO][Br2][NO], where Kc =
= K′[NO]2 [Br2]
