EXTRA CREDIT - 5 pts аvаilаble fоr Part D Questiоn appears as being wоrth 21 pts in Canvas, but 26 pts are possible. Answers to this question can be written on paper, then uploaded as a PDF in the File Uploads assignment page on Canvas after the exam. Show all calculation work, and using units and following sig fig rules in the final answer where appropriate. Fluorine-18 is a radioactive isotope commonly used in positron emission tomography (PET), an important medical imaging technique commonly used to make images of patients' brains, hearts and other organs. A. (5 pts) Write the balanced nuclear equation for the positron emission by fluorine-18. B. (8 pts) The half-life of fluorine-18 in this nuclear reaction is 109.8 minutes at 298 K. What is the rate constant, k, for this reaction at 298 K? C. (8 pts) If the entire PET process takes 120.0 minutes from the moment the radioactive isotope is injected into a patient, calculate how much fluorine-18 (as a percent) remains in the patient's body when the process is complete. D. (5 pts) Using your answer to part B, calculate the rate constant for this reaction at 350. K. Assume that the activation energy of this reaction is 22.5 kJ/mol.
