5. Analysis II. As you know, certain raw vegetables when subjected to freezing temperatures loose desirable qualities such as flavor and firmness. Suppose you are tasked with designing an inexpensive thermochromic thermometer that can be attached to vegetable shipping pallets and indicate if freezing temperatures exist. In this application the thermometer must sharply undergo a chromic shift (give a rapid, distinct color change) around 2 - 4. "C. Given the results from Questions 2 - 4 above, and assuming the and ass values of both dyes are essentially identical, which dye, BDa or BDb, would be the best choice for such a thermochromic thermometer? Clearly justify your claim using the relevant data. To receive credit, you must respond with well written, very legible, complete sentences that correctly employs chemical terminology and concepts. 3. Boa Hinn2=33.98k/mol 2. Van't Hoff Analysis. In Problem 1 above, you obtained KC at a specific temperature for BDa. In a similar manner Kc can be determined for BDa and BDb over a range of discrete temperatures. Assume, after some effort, you obtain the following Kc vs. T results for molecular dyes BDa and BDb: Ke at Various Temperatures T for BDa Kc at Various Temperatures T for BDb Using EXCEL determine AH and AS for each dye. Paste-in the plots below with the linear trend-line equation and R2 adjusted for reasonable sig figs. Remember, in this course all grophs must be appropriately scaied, titled and lobeled. Please remember to do this without further reminders. Include all calculations, that is, show all work to clearly indicate how you determined the enthalpy and entropy values for BDa and BDb. (Remember to first symbolically state the equations)
