CHEM 172 is the second semester of a one-year exploration of the fundamental concepts, principles, and practices of organic chemistry, with a focus on defining relationships between molecular structure, reactivity, and function. You (the student) will take an active role in defining questions, evaluating evidence, weighing arguments, developing and testing hypotheses, and communicating these complex topics. This study of organic chemistry will be integrated with a review of the key concepts from general chemistry and will highlight relationships with related areas including organometallic chemistry, polymer chemistry, and biochemistry. The CHEM171/172 sequence is designed for first-year students with good preparation in chemistry (2 years of general chemistry and an AP score of 4 or 5, or equivalent). This sequence provides a fast-track to advanced chemistry courses and the fulfillment of degree requirements in other disciplines. Co-registration in a workshop section is required. Co-registration in the accompanying lab—CHEM208 or CHEM210(W)—is strongly encouraged; CHM210W is recommended for CHEM majors. $134 lab fee billed by Bursar Office. Prerequisites: CHEM 171 and CHEM 173.

(4 credits, Fall, Spring) Chemistry 252 covers thermodynamics, statistical mechanics, and chemical kinetics. These subjects provide a fundamental understanding of the behavior of matter and energy. The focus of the class is on both Thermodynamics, which is the mathematical theory of heat, gives rules describing how heat flows, and the relationship between heat and other kinds of energy, as well as on Statistical mechanics, which is the discipline that explains the nature of temperature, entropy, and provides a fundamental and microscopic explanation of thermodynamics in terms of probability and laws of statistics. The course follows the textbook “Molecular Thermodynamics” by D.A. McQuarrie and John Simon, and “Molecular Driving Force” by K.A. Dill and S. Bromberg.

The course begins with the concept of Microstates and Entropy, the equal a priori probabilities assumption, the direction of approaching equilibrium as a process that maximizes the total number of microstates. It then discusses the nature of Temperature and uses heat transfer as an example to illustrate the process that maximizes the number of microstates. It continues with the derivation of the Boltzmann distribution and the physical meaning of partition function, followed by simple and concise applications of Boltzmann distribution. It then covers the factorization approximation, Translational Partition Function and Partition function of the monatomic ideal gas, obtaining energy and pressure from the partition function. It follows with the vibrational and rotational partition functions, and the intuitive understanding of heat capacities of solid and diatomic molecules. The course continues with the equipartition theorem of energy, and the concept of negative temperature. It then covers the Statistical Entropy, Entropy for model systems and detailed examples, Gibbs Entropy Formula and applications. For the Thermodynamics part of the class, it begins with the Basic logic of Thermodynamics, spontaneous processes, and the direction of approaching equilibrium. It continuous with the first law of Thermodynamics, Work, and Heat, The second law of Thermodynamics, and thermodynamics definition of Entropy, The third law of Thermodynamics, the Temperature dependence of Entropy, the concept of Enthalpy and its application in Thermochemistry. Then it follows with the Helmholtz Free energy, Gibbs Free Energy, Maxwell Relation and Gibbs-Helmholtz equation. The course then discusses the applications, focusing on Phase Equilibria, Chemical Potential, Gibbs-Duhem Equation, Solutions. It ends with the discussions of Chemical Equilibrium, Chemical Kinetics, Transition State Theory. The course also has peer-lead workshop sessions. In these sessions, students will work in teams and lead by workshop leaders to discuss concepts learned in lectures and solve problems that exemplify the concepts discussed in lecture material and explain their solutions to each other. Workshops help the students to engage with the material together with their peers. The class also contains 2-3 midterm exams and 10-11 homework problems, as well as a final exam.

This course uses the Tues/Thurs 8:00 - 9:30 am Common Exam time. Prerequisites:

General chemistry - CHM131/CHM132 or equivalent, first semester physics - PHY 113, Calculus - MTH143.

The course will familiarize the student with important modern concepts in electrochemical engineering. The first half of the course focuses on understanding the theory behind fundamental electrochemical processes. It covers mass transfer in homogeneous and heterogeneous systems, thermodynamics, charged interfaces, electron transfer kinetics, and electrochemical methods. The second half of the course introduces advanced applications, with topics including electrocatalysis and electrolysis, corrosion, photoelectrochemical devices, and flow batteries. It enables the student to quantitatively and qualitatively assess problems and empirical data from the literature, and to summarize and explain seminal and recent electrochemical engineering literature and technologies.
