ANSWERS TO CHAPTER 12 HOMEWORK 12.24 (a) For the first-order reaction, half the A molecules are converted to B molecules each minute. (b) Because half of the A molecules are converted to B molecules in 1 minute, the half- Life is 1 minute. 12.34 (a) The instantaneous rate of decomposition of N2O5 at t = 200 s is determined from the slope of the curve at t = 200s. Rate = 2.4 x 10 -5 M/s. 12.37 (a) The rate of consumption of O 2 is 1.25 times faster. (b) The rate of formation of NO is the same. The rate of formation of H 2 O is 1.5 times faster. 12.46 (a) Rate = k[CH 3 COCH 3 ] (b) k = 8.7 x 10 -3 /s (c) Rate = 1.6 x 10 -5 M/s 12.47 (a) Rate = k[CH 3 NNCH 3 ] (b) k = 2.5 x 10 -4 /s (c) Rate =5.0 x 10 -6 M/s
