Unformatted text preview: SO32- , and rate constants? d. If [SO32- >> [ArS- , what does the rate law for the reaction simplify to? Chemistry 160 problem set 10 Due Friday April 19, 2013 by 4 pm 2. The kinetics for the acid- catalyzed hydrolysis of ethyl chloroacetate and ethyl benzoate were studied at different temperatures, and the results are presented below. Ethyl chloroacetate Ethyl benzoate T (ºC) kobs (M s- 1) T (ºC) kobs (M s- 1) 24.9 3.95 x 10- 5 60.0 3.92 x 10- 6 39.8 1.35 x 10- 4 80.2 2.05 x 10- 5 - 4 60.0 6.19 x 10 99.6 8.45 x 10- 5 80.1 2.26 x 10- 3 120 3.35 x 10- 4 - 2 110 1.26 x 10 139 1.14 x 10- 3 Based on the data above: a. Provide a table that summarizes the Eact, A, ΔH‡, and ΔS‡ for both substrates. You...
