13.7 The concentration of H+ was measured at various times for the following reaction: CH 3 OH (aq) + H + (aq) + Cl - (aq) CH 3 Cl (aq) + H 2 O (l) Time (min.) [H+] (M) 0.00 2.00 50.0 1.86 150.0 1.64 300.0 1.39 650.0 1.02 (a) Determine the average rate from the initial and final times. (b) For each of the time intervals between successive measurements determine the average rate of disappearance for the hydrogen ion. (c) Construct a graph of the hydrogen ion concentration versus time. (d) Draw a tangent at 100 minutes and determine the rate at this time. (e) Draw a tangent at 325 minutes and determine the rate at this time. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50

13.9 An experiment investigating the oxidation of iodide ion by permanganate ion in acid solution found the rate of disappearance of the permanganate ion to be 4.56 x 10 -3 M/s. Determine the rate of appearance of iodine under these conditions. 10 I - (aq) + 2 MnO 4 - (aq) + 16 H + (aq) 2 Mn 2+ (aq) + 5 I 2 (aq) + 8 H 2 O (l) 13.10 The rate law for the reaction is rate = k [NH 4 + ] [NO 2 - ]. NH 4 + (aq) + NO 2 - (aq) N 2 (g) + 2 H 2 O (l) At room temperature, the rate constant is 3.0 x 10-4/Ms. Determine the rate of reaction at this temperature if [NH 4 + ] = 0.26 M and [NO 2 - ] = 0.080 M. 13.11 An investigation of the following reaction gave the data in the table for the rate of appearance of NO 2 : 2 NO (g) + O 2 (g) a 2 NO 2 (g) Experiment [NO] (M) [O2] (M) Initial rate (M/s) 1 0.0150 0.0150 2.40 x 10 -2 2 0.0300 0.0300 1.92 x 10 -1 3 0.0300 0.0150 9.59 x 10 -2 (a) What is the rate law for this reaction? (b) What is the overall order of this reaction?
