CHEMISTRY 1AA3 March 22-26, 2010 TUTORIAL PROBLEM SET 10 ________________________________________________________________________ Chemistry 1AA3 1. What are the overall orders of the reactions to which the following rate laws apply? (a) rate = k[H 2 ][I 2 ] (b) rate = k[NO 2 ] 2 [H 2 ] (c) rate = k[Cl 2 ] (3/2) [O 2 ] 2. Consider the reaction: 2 NO(g) + O 2 (g) 2 NO 2 (g) (a) Write expressions for the rate of the reaction in terms of the changes of concentrations of NO, O 2 , and NO 2 . (b) Suppose that at a particular moment the rate of reaction with respect to NO is 0.066 M s -1 . What is the rate at which O 2 is being consumed? 3. The rate law for the reaction: F 2 (g) + 2 ClO 2 (g) 2 FClO 2 (g) is rate = k [F 2 ][ClO 2 ]. At 25 ° C, the rate constant for the reaction is 1.2 M 1 s 1 . Calculate the rate of the reaction at 25 ° C if [F 2 ] = 0.010 M and [ClO 2 ] = 0.020 M. 4.
