Unformatted text preview: Nicolas E Martin- CHEM 204 Spring 2010 1 Homework 9 Due date: Fri Apr 2 23:00:00 2010 For the reaction show below determine the rate law. H 2 O 2 + 3I- (aq) + 2H + (aq) I 3- (aq) + 2H 2 O (l) The following data were obtained: [H 2 O 2 ] [I- ] [H + ] Initial Rate (mol/L s) 0.10 0.10 0.10 1.15 x 10-4 0.10 0.20 0.10 2.30 x 10-4 0.20 0.20 0.10 4.60 x 10-4 0.10 0.20 0.20 2.30 x 10-4 Calculate the rate law for this reaction: rate = k [H 2 O 2 ] [I- ] [H + ] You are correct. Your receipt is 150-6367 Initial rate data at 25 o C are listed in the table below for the reaction: 2NO(g) + Cl 2 (g) 2NOCl(g) [NO] i (M) [Cl 2 ] i (M) Initial rate (M/s) 0.13 0.20 1.0 x 10-2 0.26 0.20 4.0 x 10-2 0.13 0.10 5.0 x 10-3 First determine the experimental rate law and calculate the the value of the rate constant, k (no units). k = You are correct. Your receipt is 150-2613 Then, calculate the initial rate of this reaction, when the initial concentration of NO is 0.72 M and the inital con- centration of Cl 2 is 0.74 M? The units should be M/s. You are correct. Your receipt is 150-7324 Nicolas E Martin- CHEM 204 Spring 2010 3 Homework 9 Question 2 The following reaction: X + 2Y Z was studied by measuring the [X] as a function of time. Re-was studied by measuring the [X] as a function of time....
