Chem 444 (Physical Chemistry II), Spring 2020

Statistical Mechanics and Molecular Thermodynamics for Chemistry Undergraduates

Course Webpage: http://nanogold.org/statmech

Lectures: MWF, 10–10.50 am, Noyes 163, Dates: Jan 22–May 6

Course Objectives:

- To encourage thinking of chemical and physical processes in the language of microscopic states, stochastics, correlations, dynamics, and fluctuations (achieved through lectures and notes).

- To apply the machinery of statistical mechanics to common problems in physical chemistry, solid-state physics, and materials science (examples in problem sets).

- To appreciate the utility of this problem-solving ability to cutting edge problems of current interest (achieved through individual literature project).

Instructor: Prashant K. Jain, Associate Professor of Chemistry

Office hours: Fridays 2–4 pm in CLSL A224 (discussion of lectures, notes, problem sets, and exams)

No lectures: Mar 14–22 (Spring break)

Teaching Assistant: Jaeyoung Heo, 5th year PhD student in Prof. Jain’s lab (Email: heo8@illinois.edu, Office: A206 CLSL). Homework problem sets, solutions, and exams will be composed by Prof. Jain. All homeworks and exams will be graded by Jaeyoung in consultation with Prof. Jain.

Syllabus (Advanced topics, i.e., Chapters 5–7 will not be covered and are listed only for ambitious students)

1) The language of probabilities and microstates

2) Thermodynamic quantities, free energies, equilibrium and stability

3) The method of ensembles and partition functions

4) Ideal non-interacting systems: Quantum and classical statistics of indistinguishable particles: bosons and fermions, application to electrons in metals, phonons in crystals, photons, monoatomic and diatomic gases

5) Non-ideality: Introduction to inter-molecular forces

6) Theory of liquids and the Monte-Carlo method

7) Introduction to chemical kinetics and non-equilibrium statistical mechanics: fluctuations, time-correlations, ergodicity, transition states.

Exams and Grading:

Problem sets (10%): Four sets over semester; posted via Compass; submit answers in paper form on due date indicated in lecture unless indicated otherwise. Submissions late by one day or less will be graded but only 50% of the points earned will be awarded.

Mid-term Exam 1 (20%): Feb 24 in class. You may bring a calculator and one sheet of paper with concepts, equations, formulae, constants. 

Mid-term Exam 2 (20%): Apr 3 in class. You may bring a calculator and one sheet of paper with concepts, equations, formulae, constants. 

Literature Project (20%): Form a group (4–5 students) prior to mid-Feb, chose paper/topic due by mid-Apr, group presentations (chalk talk) on May 4 and 6.

Final Exam: (30%): May 12, 7–10 pm, Noyes 163, you may bring a calculator and one sheet of paper with concepts, equations, formulae, constants.A final exam review will be conducted by Prof. Jain in the form of office hours.
