QUESTION 30 In the reaction 2 H₂O2(aq) → 2 H₂O() + O2(g), the initial concentration of H₂O2 is 0.600M and, 28.4 seconds later, the concentration of H₂O2 is 0.330 M. What is the average rate of reaction over this time interval? O a. 0.0116 M/s O b.-0.00475 M/s OC. 0.00475 M/s O d.-0.0095329 M/s O e. 0.0095903 M/s

QUESTION 1 Predict the rate law that would result from the following two step mechanism: 2A → A2 A2+ B→A2B O Rate = k [A2B] O Rate = k [A2] [B] O Rate = k [A]² O Rate = k [A] O Rate = k [A₂] QUESTION 2 MOULICH MON MALOLCO CROUSUTHARA HATUAUIGI VHIGH (slow) (fast) The rate law for the following termolecular elementary step is: A+ B+C product(s) O Rate = k [A] [C]² O Rate = k [A]2 [B] [C] O Rate = k [B]2[C] O Rate = k [A] [B] [C]

Part A Consider the balanced chemical equation. H2O2(aq) + 3I¯ (aq) + 2H+(aq) → I3 (aq) + 2H20(1) Predict the rate of change in the concentration of H2O2 (A[H2O2]/At). In the first 12.0 s of the reaction, the concentration of I drops from 1.000 M to 0.773 M . Express the rate to three significant figures and include the appropriate units. You may want to reference (Pages 587 - 592) Section 14.3 while completing this problem. ? A[H2O2]/At = Value Units
