This course covers aspects of chemical thermodynamics and kinetics. Thermodynamics is the study of what is possible and the extent to which it is possible. Kinetics is the study of how rapidly the possible chemical transformations actually occur. The material covered here will help place your qualitative understanding of chemical reactivity from organic chemistry on a more quantitative basis. It is required for a fundamental understanding of biochemistry. Physical chemistry explores more of the underlying theories for the concepts developed here. The following areas will be emphasized: Chemical Equilibria: K eq , especially acid-base reactions; p K a , titrations, buffers. Ideal gas law. Thermodynamics: The statistical basis of the universe. Enthalpy, entropy and free energy, 1 st , 2 nd , and 3 rd laws of thermodynamics, heat capacities Relationships among thermodynamics and chemical equilibria: where does K eq come from? Electrochemistry and oxidation-reduction reactions, and their connection to thermodynamics. Batteries and electrolytic reactions. Kinetics: Maxwell-Boltzmann distribution, reaction rates and orders, elementary reactions and mechanisms, the steady state approximation, activation energy, catalysis

2 There will also be “bio-flavored” (since I am a biophysical chemist) special topics that are extensions of the core material above. Time permitting, the special topics we will cover are listed below:
