Letter or Credit/No Credit

Chem 31B is the second course in this two-quarter sequence, therefore only students who have completed Chem 31A may enroll in 31B. As with 31A, students will continue to engage in group problem-solving activities throughout class and participate in weekly laboratory activities. Labs and write-ups will allow students to more deeply explore and observe the different facets of chemical reactivity, including rates (kinetics), energetics (thermodynamics), and reversibility (equilibrium) of reactions. Through experimentation and discussion, students will determine what forces influence the rate of chemical reactions and learn how this can be applied to enzyme reactivity. Students will quantify chemical concentrations during a reaction, and predict the direction in which a reaction will shift in order to achieve equilibrium, including solubility equilibria. They will use these methods to estimate the possible levels of lead and other toxic metals in drinking water. Special emphasis will be placed on acid/base equilibria , allowing students to explore the role of buffers and antacids in our bodies, as well as ocean acidification and the impact on coral reefs. Students will then bring together concepts from both kinetics and equilibrium, in a deeper discussion of thermodynamics, to understand what ultimately influences the spontaneity of a reaction. Students will build a relationship between free energy, temperature, and equilibrium constants to be able to calculate the free energy of a reaction and understand how processes in our body are coupled to harness excess free energy to do useful work. Finally we will explore how we harness work from redox reactions, building both voltaic cells (i.e. batteries) and electrolytic cells in lab, and using reduction potentials to predict spontaneity and potential of a given reaction. We will look at the applications of redox chemistry in electric and fuel cell vehicles. The course's particular emphasis on understanding the driving forces of a reaction, especially the influence thermodynamics versus kinetics, will prepare students for further study of predicting organic chemical reactivity and equilibria from structure in Chem 33. Prerequisite: Chem 31A.

      Meets 7/20/20-8/15/20. In order to sign-up for 31B, obtain a permission number from Dr. Cardin, [email protected] Lectures and labs will be conducted through live video conferencing through Zoom. To fully engage with the course, get immediate feedback and explanations, and interact with other students and teaching staff, attendance for all live lecture and lab sections are compulsory. To access these sessions, students will need a computer, tablet, or laptop with internet access and zoom capability as well as access to a scanner or a smart phone with a scanner app to submit PDFs of homeworks, quizzes and exams (a tablet on which a student can write on pdfs for submission would also work.). A printer may be helpful for printing templates but is not required. Guided laboratory experiences, including both hands-on and virtual simulations, will be conducted in real time with the TAs during your regular lab zoom sessions. To cover the cost of materials and/or lab simulations a lab fee of no more than $100 will be charged to students after the first day of class.
