Question
1. The following kinetic data were obtained for the reaction NO2 (g) + O3 (g) ? NO3 (g) + O2 (g) Experiment [NO2], M [O3], M initial rate (M/s) 1) 0.21 x 10-3, 0.70 x 10-3 6.3 x 10-3 2 ) 0.21 x 10-3 1.39 x 10-3 12.5 x 10-3 3 ) 0.38 x 10-3 0.70 x 10-3 11.4 x 10-3 4) 0.66 x 10-3 0.18 x 10-3 ? A Write the rate law for this reaction (show your work). B What is the order of the reaction (overall)? C. Determine the value of the rate constant (with the correct units). d. Predict the rate of the reaction in experiment 4 based on the determined rate law.Explanation / Answer
If it is zero order in "A", "A" does not appear in the rate law eqtn.
If "A" is doubled, it has nothing to do with the rate law.
If "B" is half-order, "sqrt(B)" is in the rate eqtn. If "B" is increased by some factor like "m" times, the rate increases by sqrt(m) times.
If "C" is 2d order, "C^2" is in the rate eqtn. If "C" is increased by some factor like "m" times, the rate increases by m^2 times.
This should solve most of your questions. Just think thru it.
