Consider the following two proposed mechanisms for the overall equation A + B2 → C
Mechanism I
B2 + M ↔ 2B + M (K1)
B + A+ M ↔ AB+M (K2)
AB + B2 → C + B (slow step, rate determining step)
Mechanism II
B2 + M → 2B + M (slow)
B + A → AB (slow)
AB + B2 → C + B (slow)
2B → B2 (slow)
Do both mechanisms give the same expression for dC/dt?

Do you have any idea?
