Rate law: r = K[A]^-1[B]^2. Incorrect information: — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

(b) A in excess: r ≈ K'[B]^2 (second-order in B); half-life of B increases over time (correct). (d) [A]=[B]: r ≈ K[A] (first-order effectively); equal half-lives (correct). Therefore (a) and (c) are incorrect.
