Entropy and Free Energy

Entropy and Free Energy

Author: carolyn fruin

Learning Targets:

  • I can explain the relationship between enthalpy change or entropy change and the tendency of a reaction to occur.
  • I understand the concept of free energy.
  • I can calculate the free energy of a reaction and predict whether a reaction is spontaneous or nonspontaneous.
  • I know that when a reaction is spontaneous it means that it can occur but does not guarantee that it will occur.

Entropy Power Point (17-2)

This power point describes the second driving force of chemical reactions. Gibbs free energy is also introduced as a mathematical relationship between enthalpy and entropy and how you can use it to predict the spontaneity of a chemical reaction.
