Be sure to answer all parts. the bromination of acetone is acid-catalyzed: ch3coch3 + br2 h+ 20140509164609authoringinterface ch3coch2br + h+ + br− the rate of disappearance of bromine was measured for several different concentrations of acetone, bromine, and h+ ions at a certain temperature: [ch3coch3] (m) br2 (m) [h+] (m) rate of disappearance of br2(m/s) (1) 0.500 0.0500 0.0500 5.24 × 10−5 (2) 0.500 0.100 0.0500 5.24 × 10−5 (3) 0.500 0.0500 0.100 1.05 × 10−4 (4) 0.665 0.0500 0.200 2.78 × 10−4 (5) 0.665 0.0500 0.0500 6.97 × 10−5 (a) what is the rate law for the reaction? rate=k[ch3coch3]2[br2]2[h+] rate=k[ch3coch3]2[br2][h+] rate=k[ch3coch3][br2]2[h+] rate=k[ch3coch3][br2][h+]2 rate=k[ch3coch3][br2][h+] rate=k[ch3coch3][br2] rate=k[ch3coch3][h+] rate=k[br2][h+] rate=k[ch3coch3] rate=k[br2] rate=k[h+] (b) determine the rate constant using the data from experiment (1). report your answer to 3 significant figures. k =

Which produce would best increase the amount of heat energy that is actually gained by calorimeter b

13. calculate the initial concentration (before precipitation) of carbonate ions after the addition of each 0.05 ml of solution b to the 1.00 l beaker of solution a. divide the work among group members and write the answers in the table in model 3. assume the volume change as solution b is added is negligible. 14. notice the initial concentrations of zn2+ - and cu2+ in the table in model 3. a. explain how these were obtained from the data in model 2. b. as solution b is added and precipitates form, do these initial concentrations change? 15. use the data in model 2 to indicate the presence of precipitate (either znco3 or cuco3) after each 0.05 ml addition of solution b in model 3. 16. use the initial concentrations of carbonate ions and zinc ions to calculate the reaction quotient, qsp for the zinc carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3. 17. use the initial concentrations of carbonate ion and copper(ii) ions to calculate the qsp for the copper(ii) carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3.

Suppose that during that icy hot lab 65,000 j of energy were transferred to 450 g of water at 20°c what would have have been the final temperature of the water
