CH13-LECT5PROB Page 1 CHAPTER 13 PROBLEM SOLUTIONS 1. State two quantities that must be measured to establish the rate of a chemical reaction. Cite several factors effecting the rate. 2. Explain why the rate of formation of formation of N 2 and the rate of disappearance of NO are not the same in the reaction: 2 CO + 2 NO 2 CO 2 + N 2 5. What variables are related through the rate law of a reaction , and what variables are related through the integrated rate law ? Write the two equations for the first order reaction: N 2 O 5 2 NO 2 + ½ O 2 6. For the reaction A products, a plot of [A] versus time is a straight line. What is the order of this reaction ? 7. The reaction 2 A + B C + 2 D is first order in A and first order in B. For this reaction a) b) c)

CH13-LECT5PROB Page 2 d) 8. A first order reaction has a half-life of 13.9 min. The rate at which this reaction proceeds when [A] = 0.40 M is 9. The rate of a chemical reaction generally increases rapidly , even for small temperature increases, because of a rapid increase with temperature with the: a) collision frequency b) fraction of molecules with energies > E act c) activation energy d) average kinetic energy of molecules 10. Why is the orientation of the colliding molecules an important factor in determining the
