  2. 1. For the reaction: 2 NO + Br2 2 NOBr • GIVEN: Rate = k [NO]2 [Br] • the following data was collected! • EXPERIMENT [NO], M [Br], M Rate, M min-1 • 1 1.0 1.0 1.3 x 10-3 • 2 2.0 1.0 ? • 3 ? 2.0 2.6 x 10-3 • a. (4 points) Complete the table by determining the missing data from the given rate law? • b. (4 points) Calculate the value of the rate constant for the same reaction?

  3. 2. For the reaction: • 2 A + B + 3 C  D + E • EXPERIMENT [A]0 [B]0 [C]0 Rate(M sec-1) • 1 0.70 0.12 0.23 0.049 • 2 0.35 0.12 0.23 0.024 • 3 0.35 0.12 0.69 0.220 • 4 0.70 0.48 0.23 0.049 • a. (4 points) Using the data above, derive the “Rate Law” for the above reaction? • b. (4 points) Calculate the value of the rate constant for the same reaction.
