Daily Objective:
Students will analyze reactions to determine the rate at which they occur, and will be able to predict the rates of various reactions.
Bellwork:
The reaction
5Br− (aq)
+ BrO3− (aq) + 6H+ (aq) → 3Br2
(l) + 3H2O (l)
is expected to obey the mechanism
BrO3−
(aq) + H+ (aq) → HBrO3 (aq)
HBrO3 (aq)
+ H+ (aq) → H2BrO3+ (aq)
H2BrO3+
(aq) + Br− (aq) → (Br—BrO2)
(aq) + H2O (l)
(Br—BrO2) (aq) + 4Br− (aq) + 4H+ (aq) → products
If the rate law for this reaction is Rate = k[BrO3-][Br-][H+]2, which step in the mechanism above is the slow step? Explain your answer.
