Question
Questions 29 and 30 concern the reaction and mechanism below.
The formation of NOBr,
2 NO(g) + Br2(g) → 2 NOBr(g),
is studied, and the following mechanism is proposed:
NO(g) + Br2(g) ⇌ NOBr2(g) fast, equilibrium
NO(g) + NOBr2(g) → 2 NOBr(g) slow
What rate law is predicted by this mechanism?
A.
Rate = k[NO][Br2]
B.✓ Correct
Rate = k[NO]^2[Br2]
C.
Rate = k[NO][Br2]^2
D.
Rate = k[NO]^2
