What This Document Is
This document is a lab report detailing an experiment conducted in Introduction to Physical Chemistry Laboratory (CHEM 3851) at East Carolina University. The experiment focuses on determining the enthalpy of combustion for naphthalene using an oxygen bomb calorimeter. The report outlines the process of calibrating the calorimeter with benzoic acid and then applying that calibration to measure the enthalpy of combustion of naphthalene, ultimately comparing the experimental result to the known literature value.
Why This Document Matters
This lab report is essential for students enrolled in CHEM 3851. It serves as a record of experimental procedures, data collection, and analysis. Understanding this experiment is crucial for grasping fundamental concepts in thermochemistry, calorimetry, and the application of these principles to real-world chemical processes. It’s typically used for assessment of practical skills and understanding of theoretical concepts.
Common Limitations or Challenges
This report presents the *results* of an experiment, but it does not provide a comprehensive guide to calorimetry itself. It assumes prior knowledge of basic chemistry principles and laboratory techniques. The report focuses specifically on naphthalene and benzoic acid; it doesn’t cover the broader application of oxygen bomb calorimetry to other substances.
What This Document Provides
The full lab report includes: a detailed introduction to the concepts of enthalpy of combustion, calorimeter constants, and relevant chemical properties; a theoretical framework explaining the underlying principles of the experiment; a comprehensive list of the chemicals and equipment used; a detailed experimental procedure; the raw data collected during the experiment; calculations performed to determine the enthalpy of combustion; an analysis of the results, including percent error; and a link to the Material Safety Data Sheet for Benzoic Acid.
This preview *does not* include the raw data, calculations, or the full results analysis. It provides an overview of the experiment’s purpose and scope.
