CHEM 152 – Spring 2021 Dr. Gillette Page 1 of 4 Final Exam Topics List The Final Exam will take place on Wednesday, May 19th at 8 am, and will be 90 minutes long. The exam will be on Blackboard and will be closed book and closed notes. A periodic table and the following information will be given, along with any data that you need (thermodynamic data, Ka values for specific acids, etc.) ΔG = ΔH - TΔS R = 8.314 J/mol K = 0.08206 L atm / mol K ΔTb = kbm P = XsolventPsolvent q= CmΔT ΔTf = −kf m Π = MRT Kp=Kc(RT)Δn ln[A] = ln[A]0 – kt [A] = [A]0 - kt ?? = ???? −????? ???? ???? = ?????? + log ?? ?????????? = ?????????? − 1 atm = 760 torr = 101325 Pa ?? ???? ???? ln ?? ???? ??? = ??? ?? + ???? ln ?? ?? = ln ? −?? ± √?? 2 − 4???? 2?? ??1 −???? 1 1 ?=? ?? − ? ??2 ?? ??1 ??2 ??? ?? = −?????? ?? F = 96, 485 The following topics may be covered. Remember that you are responsible for material covered in class. I will not ask questions from the textbook if we did not discuss the topic in class. Each topic has the sections in the book that correspond, and well as suggested end-of-chapter problems for extra practice. Remember, the answers to all odd-numbered end of chapter problems are in the back of the book! New material since Exam 2 is highlighted yellow.
