A student conducts two experiments involving the reaction below. For this reaction, the experimentally determined differential rate law is rate = k[S2O82-] [I-] S2O82-(aq) + 3 I-(aq) --- 2 SO42-(aq) + I3-(aq) In the first experiment, she finds that if the initial concentration of [I-] is 0.072 M, the concentration of [I-] after 400.0 seconds is 0.057 M. She conducts a second experiment in which the initial concentration of [I-] is 0.100 M. What will [I-] be after 800.0 seconds during the second experiment? Show all work and write your answer in the same provided below with appropriate units. Assuming that the concentration of products is zero at the start of the reaction, what will [SO42-] be after 800.0 seconds during the second experiment? Show all work and write your answer in the space provided below with appropriate units. Hint: What is the average rate of the reaction with respect to [SO42-] for the first 800 seconds of this reaction?
