Up: Back to the Chemistry 2710 test index Chemistry 2710 Spring 2000 Test 1 Solutions 1. If we look at the first two experiments, we see that the rate doubles when the ozone concentration doubles. Comparing the first and third experiments, the rate triples when the ozone concentration triples. The order with respect to ozone is therefore one. Similarly, if we compare the third and fourth experiments or the third and fifth, we see a simple proportionality between the rate and nitrogen monoxide concentration. It follows that the rate law is The rate constant can be calculated from any one of the experiments, for instance the first one: 2. It could be elementary. It involves only two reactants. One can imagine the transfer of an oxygen atom from one molecule to another occuring in one step. Moreover, the rate law is consistent with this being an elementary reaction. 3. B is an intermediate. It should not show up in the overall reaction. To eliminate it, we add twice the second reaction to the first. The result is
