Continuing with your study of the degradation kinetics of Y in the presence of excess H+ so that [H+] >> [Y], you are interested in finding the activation energy, Ea,. Recall Y has a unique lmax at 254 nm, with a molar absorptivity ε of 4.55 x 103 cm-1 M-1 at 254 nm and the optical path length of b = 1.00 cm. The following data is collected from samples of Y with a starting (initial) concentration of 1.49 x 10-4 M:

1. Rate Constant kobs vs. Temperature T (12p). Build a summary table based only on the data from the previous page. In the table present the observed rate constant kobs values at the five different temperatures, T. Show all the graphical work, by pasting in all five EXCEL graphs (one for each temperature) below. Remember to properly title the plots, label the axes correctly and include the linear trend-line equations and R2 values. The summary table requires a title and properly labeled columns.
2. Activation Energy Ea (5p). Using EXCEL prepare an ln(kobs) vs. 1/T plot from the Question 1 kobs vs. T summary table that can be used to determine the activation energy Ea for the system. Paste-in this plot below and give the linear trend-line equation and R2 value (from EXCEL). State the Ea thus obtained. Show all work, explaining clearly how you derived the value of Ea from this plot.
3. Half-Life at 37.0 °C (5p). For the experimental conditions of the degradation study, calculate the t1/2 (half-life) for Y at 37.0 oC. Use equation (6) from the accompanying guide and the kobs at 23.5 oC from Lab Assignment 5. Show all work. Symbolically state the equations you are using. (Hint, the material in Unit 5 Module 3 under “Temperature Effects” may prove helpful.)
4. Percent of Drug Y Remaining (3p). For the experimental conditions of the degradation study, calculate the percent of drug Y remaining after 8.00 hours at 37.0 oC. Show all work. Symbolically state the equations you are using.
