Question
For the reaction
O2(g) + 4 HBr(g) → 2 H2O(g) + Br2(g)
the following mechanism is proposed:
O2(g) + HBr(g) ⇌ HOOBr(g) fast, unfavorable
HOOBr(g) + HBr(g) → 2 HOBr(g) slow
HOBr(g) + HBr(g) → H2O(g) + Br2(g) fast
What rate law is predicted by this mechanism?
A.
Rate = k[HBr]
B.
Rate = k[O2][HBr]
C.✓ Correct
Rate = k[O2][HBr]2
D.
Rate = k[O2][HBr]4
