Chapter 20: Spontaneous Change: Entropy and Free Energy Web Resources

This module provides current links to other websites that allow you to explore the world of chemistry more. First, we offer links to plug-ins and other software that enable your browser to take full advantage of the material on these sites. Second, there are links of general interest to general chemistry students. Third, there are resources that are specifically aimed at the topics in this chapter.
