Course Description

This course relates molecular-level descriptions of matter to the large-scale properties and behaviors displayed by bulk materials. We will begin with a discussion of the bulk properties of gases, including deviations from ideal gas behavior. This will be followed by a short excursion into molecular energies, the Boltzmann factor, and partition functions. We will examine how these molecular-level descriptions can be related to the bulk properties of ideal gases. A major portion of the course will be devoted to exploring the consequences of the laws of thermodynamics, using ideal gases and other simple models to investigate thermochemistry, chemical equilibrium, phase diagrams, solutions, electrochemistry and kinetics.

Course Objectives

At the end of this course, you should be able to
  • Apply the basic tools of calculus to concepts in chemistry.
  • Manipulate the gas laws to describe real and ideal gas behavior.
  • Discuss the Three Laws of Thermodynamics and their development.
  • Use the Maxwell equations and other thermodynamic relations to compute thermodynamic quantities from thermodynamic data tables.
  • Be able to derive relationships between thermodynamic quantities.
  • Interpret phase diagrams and discuss phase equilibria in terms of chemical potential.
  • Explain the origin of the equilibrium constant and its relationship to fugacity and activity, and apply these concepts to real and ideal solutions.
  • Use the Boltzmann distribution to describe the energy distribution associated with a chemical system at equilibrium.
  • Use the results of quantum mechanics to evaluate molecular and canonical partition functions.
  • Relate the canonical partition function to the thermodynamic energy and entropy.
  • Use kinetic information to arrive at plausible reaction mechanisms and/or rate laws.
  • Apply the steady-state hypothesis to obtain rate equations.

Meetings and Announcements

The lecture meets in Payson Smith 203 (Portland), Mondays and Wednesdays from 11:45 to 1:00, weather permitting. (Check the USM storm line, 780-4800, for cancellations.) Any changes to the schedule, syllabus, etc. will be announced in class. You are responsible for all such announcements, whether you attended class or not.

Evaluation

Homework and in-class assignments will count for 40% of your grade. There will be 2 in-class exams and a final, each worth 20% of your grade. All exams are cumulative, but will emphasize material covered since the previous exam.
