9. For the reaction given, the [1] changes from 1.00 M to 0.868 M in the first 10 seconds. Calculate the average rate in the first 10 seconds: H2O2(aq) + 31'(aq) + 2H+ (aq) 13(aq) + 2H2O(1) If, in this reaction, water is formed at a rate of 1.25 M/s, at what rate is oxygen being consumed? a) 4.40 x 10-2 M/s b) 8.80 x 10 M/S c) 13.20 x 10 M/S d) 1.88 M/s e) 2.19 M/S 10. What experimentally-determined rate law would be consistent with the two-step mechanism shown below? (1) A + B SC (fast, rapid equilibrium) (2) B + C 2D (slow, rate-determining step) a) rate = k [A] [B] b) rate = k[B][C] c) rate k[A] [B] d) rate = k[A] [B] e) rate = k[A] [C]
