Unformatted text preview: First note that the initial rate follows the line drawn diagonally across the graph. The line is labeled as being at a 45 degree angle with the x-axis. That means the rise eqquals the run and the slope, [ A ] s , equals one, so the initial rate is 1 M/s. You are given k and from the units you should be able to tell it is a 2 nd order reaction. So the rate law is Rate = k [ B ] 2 . If you substitute in the information you know: 1 M s = 0.25 M − 1 s − 1 [ B ] 2 1 = 1 4 [ B ] 2 [ B ] 2 = 4 [ B ] 2 = 2 M...
