###### Course Synopsis

statistical thermodynamics: • Explanation (quantitative) of the properties of macroscopic systems (e.g. thermodynamic functions) using the knowledge of the properties of individual molecules (obtained from molecular spectroscopy or quantum chemistry) • Providing rigorous definitions of thermodynamic quantities and derivations of the laws of thermodynamics from the laws of quantum mechanics. • Obtaining information on the properties of single molecules and their interaction from the knowledge of macroscopic (bulk) properties of matter Electro Chemistry: • Describe how a galvanic (voltaic) cell operates, with the concepts of electrodes, salt bridges, half-cell equations, net cell reaction, and cell diagram. • Write an accurate cell diagram for a given cell, or describe a cell from a cell diagram. Understand and explain the role of inert electrodes. • Describe the standard hydrogen electrode and explain how other standard electrode potentials are related to it. • Use tabulated standard potentials, Eoredox. Eoox, to compare the reducing/oxidizing strength of species involved in redox reactions.

###### Course Learning Outcomes

Statistical Thermodynamics: On completion of the course, students will be able to: • Understand the laws of thermodynamics and a systematic definition of thermodynamic potentials as general formalism of thermodynamics. • Learn to recognize, define, and solve problems in equilibrium and statistical thermodynamics. • Student recognizes the difference between temperature and heat. • Account for the physical interpretation of partition functions and be able to calculate thermodynamic properties of model systems. • Account for the physical interpretation of distribution functions and discuss and show how these can be used in calculations of basic thermodynamic properties. • Account for the fundamental ideas in the Debye-Huckel theory and use the theory for calculations of properties of electrolytes. • Identify the relationship and correct usage of infinitesinal work, work, energy, heat capacity, specific heat, latent heat, and enthalpy. Electro Chemistry: completion of the course, students will be able to: • Recognize oxidation reduction (redox) reactions and be able to:  assign oxidation numbers to atoms in molecules and ions  write the oxidation and reduction half reactions  identify the compounds being oxidized and reduced  identify the oxidizing agent and reducing agent  balance a redox reaction by the half-reaction method • Describe the functions of the various components of simple voltaic and electrolytic cells. • Diagram electrochemical cells, labeling the anode, cathode, and directions of ion and electron movement. • Given appropriate reduction potentials,  calculate the cell voltage (standard cell potential) generated by a voltaic cell  determine the relative strengths of oxidizing or reducing agents  use standard reduction potentials to predict whether a given reaction will be spontaneous when all of the reactants and products are present in their standard states (under standard conditions) • Understand the relationship between Eo cell, ∆G°, and K for oxidation-reduction reactions and be able to:  calculate ∆G° from Eo cell and perform the reverse operation  calculate K from Eo cell and perform the reverse operation • Use the Nernst equation to calculate the cell potential or the concentration of a substance under nonstandard conditions. • Discuss how a spontaneous redox reaction can be used to create a battery and  recognize the connection between the components of the cell and the properties of the battery  recognize the chemical reaction used in a lead-acid storage battery and lithium ion battery  Discuss the difference between galvanic and electrolytic cells and: calculate the time, current, and the amount of substance produced/consumed in an electrolysis reaction.
