A reaction involves two intermediates, I1 and 12. Which of the following statements about the reaction mechanism is incorrect? A k₁ k.1 11 k₂ k_2 12 A k3 If the 12 G step is rate-limiting, then the overall rate law is second order with respect to [A]. If k3 [A] » k₂, then [12] is very close to 0. If the 11 →→ 12 step is rate-limiting, then it cannot be reversible and k-2 = 0. A reasonable starting point to solve the rate law is vo= k3[12][A].

Question
A reaction involves two intermediates, I1 and I2. Which of the following statements about the reaction
mechanism is incorrect?
A
k₁
k.1
k_₂
12
A
k3
If the 12 → G step is rate-limiting, then the overall rate law is second order with respect to [A].
If k3 [A] » k2, then [12] is very close to 0.
If the Il → 12 step is rate-limiting, then it cannot be reversible and k_2 = 0.
A reasonable starting point to solve the rate law is vo = k3[12][A].
