Gibbs Free Energy

Energy is neither created nor destroyed, but what about free energy? Where does that fit into thermodynamics? In the video, learners explore simple the spontaneous reaction examples of enthalpy, entropy, and temperature, and then apply them to Gibbs free energy reaction. Free energy is then applied to cellular respiration and photosynthesis.

Instructional Ideas

  • Further explore entropy and enthalpy in class
  • Preselect other examples of spontaneous reactions and analyze them using Gibbs free energy equation
Classroom Considerations

  • Need a computer, Internet access, and projection system to complete the activity
  • You may want to show the previous video, as there is some repetition between the two
  • Part 21 in a series of 37

  • Begins with simple explanations and then applies them to biological concepts 
  • Includes review worksheet

  • None
