## KINETICSQUIZ(20 points)

• 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

• 22.0 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?

• 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 0.230.049

• 2 0.35 0.12 0.230.024

• 3 0.35 0.12 0.690.220

• 4 0.70 0.48 0.230.049

• 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.

• 3. (4 points) Write a rate law using the mechanism below?

• CO2 (g) + OH-  HCO3- SLOW

• HCO3- + OH- CO32- +H20 FAST
