Document Summary
Do not write on this exam!: multiple choice: read each question and all of the choices. Select the best answer for each question and mark your answer on your scantron. (5 points each, total is 100 points: write a balanced reaction for which the following rate relationships are true. N2o: 2 n2o 2 n2 + o2, 2 n2 + o2 2 n2o, n2o n2 + 2 o2, given the following balanced equation, determine the rate of reaction with respect to [nocl]. If the rate of cl2 loss is 4. 84 10-2 m/s, what is the rate of formation of nocl: 4. 84 10-2 m/s b) 2. 42 10-2 m/s c) 1. 45 10-1 m/s d) 9. 68 10-2 m/s. 2 no(g) + o2(g) 2 no2(g: rate = 57 m-1s-1[no][o2, rate = 3. 8 m-1/2s-1[no][o2]1/2, rate = 3. 1 105 m-3s-1[no]2[o2]2, rate = 1. 7 103 m-2s-1[no]2[o2, rate = 9. 4 103 m-2s-1[no][o2]2.
