both exams are in class
suggested text: D = Denbigh, Principles of Chemical Equilibrium:

The above reading assignments are MINIMA; read more in your text, and in books you can find in EPSL, HORNBAKE, and the CHEM LIB; also see J. Chem. Educ., The Physics Teacher., and various volumes of Reviews in Mineralogy. The more outside thought, reading and problem solving you do during and AFTER this course, the better you will understand the "thermodynamic view" of planets and the universe, and the better you will be at performing geochemical and geophysical calculations.

HONOR CODE: The University has a nationally recognized Honor Code, administered by the Student Honor Council. The Student Honor Council proposed and the University Senate approved an Honor Pledge. The University of Maryland Honor Pledge reads:

 "I pledge on my honor that I have not given or received any unauthorized assistance on this assignment/examination."

Unless you are specifically advised to the contrary, the Pledge statement should be handwritten and signed on the front cover of all exams submitted for evaluation in this course. Please adhere to the code of Academic Integrity.
