______________________________________________________________________________ Chemistry 5.68J Chemical Kinetics Spring Term 2003 Chem. Eng. 10.652J Kinetics of Chemical Reactions Problem Set #2 Due: February 25, 2003 1. CKD Problem 2.4 2. CKD Problem 2.6 3. CKD Problem 2.9 4. CKD Problem 2.15 5. Some complex reactions involving the oxides of nitrogen, with their empirical rate laws, are: overall reaction empirical rate law 1) 2N 2 O 5 4NO 2 +O 2 R 1 =k 1 [N 2 O 5 ] 2) NO + N 2 O 5 3NO 2 R 2 =k 2 [N 2 O 5 ][NO]/{[NO 2 ]+ α [NO]} 3) 2NO 2 +O 3 N 2 O 5 +O 2 R 3 =k 3 [NO 2 ][O 3 ] R 4 =k 4 [N 2 O 5 ] 2/3 [O 3 ] 2/3 4) 2O 3 +N 2 O 5 3O 2 +N 2 O 5 Mechanisms for reactions (1) – (4) can be constructed from the following elementary reactions: (a) N 2 O 5 NO 2 +NO 3 (b) NO 2 +NO 3 NO 2 +NO + O 2 (c) NO + NO 3 2NO 2 (d) NO 2 +O 3 NO 3 +O 2 (e) 2NO 3 2NO 2 +O 2 (f) NO + O 3 NO 2 +O 2 (g)
