Thermochemistry and Energy Use
Contributors
Summary
This module focuses on thermochemistry, which is covered in either general chemistry I or general chemistry II depending on institutional preferences. The module consists of several activities.
Activity 1 consists of an initial orientation to energy systems: completed by students outside of class and followed by an an in-class activity where students calculate the energy required to prepare food both one time and over the course of a year; products created by the generation of energy for kitchen use; and the energy saved by reducing solvent usage in the synthesis of compounds used in PCR testing for COVID-19.
Activity 2 is designed to be completed outside of class and focuses on connections between energy usage and economic/social considerations. Activity 3 includes an introduction to renewable energy and problems to be done in class or as homework where students: calculate the energy of a phase change; calculate the change in energy for various physical and chemical processes, using Hess’s law and other thermochemical concepts; examine components of hydrogen storage systems; and evaluate different methods of hydrogen storage.
The GCTLC learning object external link takes you to the ACS GCI website to download the learning materials. Once there, use the Module Overview document to guide you through using these impactful learning materials.
This module was developed by Matt Fisher and Jennifer Tripp for the green chemistry educational module project with the American Chemical Society Green Chemistry Institute; Sarah Kennedy and David Laviska reviewed and published the module.
