Module 1—Thinking Energy

Lesson Summary

In Lesson 5 you considered the following question:

• How can the energy richness of different fuels be compared?

Molar enthalpy of reaction is a value describing the energy change associated with a chemical process per mole of one of the reactants or products involved in the process. In this lesson you calculated a molar enthalpy for a neutralization reaction, and you used molar enthalpy values to compare different fuels per mole of fuel.

As society is becoming more aware of humanity's impact on the environment, people are attempting to ”go green.” Your tour participants will expect your ecotour to use energy-rich alternative fuels.
