What This Document Is
This document is a completed solution set for Preliminary Exam 2 in Cornell University’s Engineering General Chemistry (CHEM 2090) course, taught by Professor Marohn, from the Spring 2014 semester. It represents a student’s completed exam, showcasing answers and work for a range of chemistry topics.
Why This Document Matters
This resource is valuable for students currently enrolled in or having recently completed CHEM 2090, or a similar general chemistry course. It serves as a study aid for understanding the expected format, difficulty, and scope of exams. It’s particularly useful for self-assessment and identifying areas where further review is needed. Students can compare their own approaches to problem-solving with the provided solutions.
Common Limitations or Challenges
This document is a *completed exam*, not a teaching tool. It does not provide explanations of underlying concepts or derivations of equations. It assumes a base level of understanding of the course material. Relying solely on this document without engaging with lectures, textbooks, and problem sets will likely be insufficient for mastering the material. It is a snapshot of one student’s work and may not represent all possible solution paths.
What This Document Provides
The full document includes:
* Detailed solutions to exam questions covering Entropy, Chemical Equilibrium (Parts I & II), Quantum Mechanics (The Quantum World, Matter Waves, Atomic Quantum Mechanics), and Molecular Structure.
* Worked problems demonstrating application of chemical principles.
* A copy of the original exam questions.
* A periodic table, physical constants, and equations are included on the final page.
This preview *does not* include the full solutions to all problems, only excerpts from the Entropy and Chemical Equilibrium sections. It does not provide explanations of the concepts tested.
