What were the units for k' written above? Explain your answer. 4. Use the slope of the plot you selected in the previous step to find the value of k'. 5. Attach all three plots to your report. Be sure to appropriately title! 6. Repeat steps 1-5 for experiment 2. PHE > ctrl T Name: B. Determination of order by graphing 1. Use the data from experiment 1 to construct the following plots (each plotted separately) with Excel: : VS. t Ax-A In (A-A) VS. t 1/(A.-A) vs. t {zero order plot} {first order plot} {second order plot} 2. Now, use the trend line option to add the best straight line to each plot. Be sure to have it display both the equation and the R value. 3. The plot that most nearly approximates a straight line (look at the R value) will tell you the order in chromium. : 7 ? < La
