Average Rate of Reaction

Q. 1. Consider the reaction A2 + B2 ⇌ 2AB. If the initial concentration of both A2 and B2 is 4.0 M, and after 10 minutes the reaction appears to stop. The concentration of [A2] is now 2.0M. a. Draw a graph of [A2] vs. time, over the span of minutes. b. On the same axes draw a graph of [B2] v time, over a span of 20 minutes. c. On the same axes draw a graph of [AB] v time over a span of 20 minutes. d. We discuss the rate in terms of [A2], [B2], or[AB]. How are they related to each other? -Δ[A2]/Δt = ? e. What is the difference between Δ[A2]/Δt and d[A2]/dt? f. Att = 15 minutes has the reaction actually stopped? Explain your answer at the macroscopic level and the molecular level.

Average Rate of Reaction

Q. Suppose you are studying the catalyzed decomposition of hydrogen peroxide. 2H2O2⟶2H2O+O2. If you collect a 4.73 mL of O2 at 298 K and 1.00 atm over 60.0 seconds from a reaction solution of 4.39 mL, what is the initial rate of the reaction? So I know that the Rate law indicates that rate= -1/a * delta A / delta t = 1/b * delta B/ delta t. I'm not sure how to implement it into this question. So far I think it could be: -1/2 * delta H2Os / delta t = 1/2 * delta H2O / delta t = delta O2 / delta t. What is delta in this case.
