What This Document Is
This document is a closed-book preliminary exam (Exam 2) for Cornell University’s Engineering General Chemistry (CHEM 2090) course, taught by Professor Marohn in Spring 2014. It assesses student understanding of key concepts covered in the course up to April 15, 2014. The exam is designed to be completed within a 90-minute timeframe.
Why This Document Matters
This exam is valuable for students currently enrolled in or preparing for CHEM 2090 at Cornell. It serves as a practice tool to gauge preparedness for similar assessments. Past exams provide insight into the professor’s testing style, the types of questions asked, and the relative weight given to different topics. It’s also useful for students seeking to understand the scope of material covered in the course.
Common Limitations or Challenges
This is a past exam and may not perfectly reflect the content or format of current assessments. Solutions are not included, making it a self-assessment tool only. The exam focuses on a specific point in the semester and doesn’t represent a comprehensive review of the entire course.
What This Document Provides
The full exam includes eight sections covering: Entropy, Chemical Equilibrium (Parts I & II), The Quantum World, Matter Waves, The Periodic Table, and Atomic & Molecular Quantum Mechanics. Each section is worth 25 points, for a total possible score of 200. The document contains a mix of conceptual questions and quantitative problems requiring calculations. A periodic table, physical constants, and relevant equations are provided at the end of the exam (page 12). This preview shows the exam’s front page, the Entropy section with a multi-part problem, and portions of the Chemical Equilibrium and Quantum World sections, including multiple-choice questions. It does *not* include the complete exam questions, solutions, or the final reference material page.
