  • Class notes • 27 pages • 2022
  • CHEM 103 MODULE 3 NOTES. 3.1: THERMOCHEMISTRY Thermodynamics is the study of the relationship between heat and other forms of energy, particularly mechanical work. Thermochemistry is the part of thermodynamics that deals with the quantity of heat given off or absorbed during a chemical reaction. The quantity of heat given off or absorbed during a physical change or temperature change can also be studied, and we will refer to this process as calorimetry. In order to adequately discuss thermoch...

Hess's Law
  • Hess's Law

  • Summary • 9 pages • 2024
  • The PDF explains Hess's Law, which states that the total enthalpy change of a chemical reaction is independent of the reaction pathway as long as the initial and final conditions are the same. It introduces Hess cycles, illustrating how to use them to calculate enthalpy changes that cannot be determined experimentally. The document includes worked examples, such as calculating enthalpy changes and bond energies using energy cycles, providing step-by-step guides for solving these problems. It ...
