Introduction to Thermochemistry (START HERE)

4. Energy in Chemical Reactions

In Module 2 you will keep investigating energy changes in chemical reactions by focusing on changes that occur at the molecular level.

You will continue the ecotour planning you began in Module 1 by considering using biodiesel in vehicles required by your ecotour. Biodiesel is an alternative fuel that can be produced from waste cooking or other oils. You will consider the production and use of biodiesel from a variety of perspectives.

In Module 2 you will investigate the following question:

• What energy changes must be considered when designing chemical systems?

You will also continue to address the Module 1 questions:

• Should energy be given a higher priority when making decisions about society’s future?

• How does society use the energy of chemical changes?

• What are the impacts of energy use on the environment?

• How does society use knowledge of the energy associated with chemical processes to promote sustainability?

• In what ways have issues of energy use affected the development of past and present societies?
