Stoichiometry: Combustion, Fuels, and Green Chemistry Metrics
Contributors
Summary
This module connects ideas across topics in a first semester introductory chemistry course to explore the impacts of combustion reactions. By motivating students to understand the relationship between reaction completion and yield, and molar enthalpies and reaction efficiency in the context of selecting fuels for a fire, educators can explore both safety and sustainability without additional materials.
Each of the two units focuses on a different green chemistry principle. The first examining stoichiometry explores the impacts of low yields such as carbon monoxide from incomplete combustion. By exploring the impacts of incomplete combustion we can examine the downstream effects and importance of waste prevention. Using GCP #2 Atom Economy students evaluate the impacts of reactants forming byproducts and waste products from reactions. Also in the second unit students work to select appropriate fuels for a given context and compare fuel efficiency metrics.
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 Julian Silverman and Jessica D'eon for the green chemistry educational module project with the American Chemical Society Green Chemistry Institute; Sarah Kennedy and David Laviska edited, reviewed, and published the module.
