  1. Heat and Work

  2. Sign Convention

  3. Heat and Work Exchange Due to A Chemical Reaction

  4. Enthalpy Change Change in enthalpy for a process at constant pressure and when there is only PV work

  5. Change in Standard Enthalpy of Reactions

  6. Dispersion of Energy

  7. Entropy vs. Temperature

  8. Change in Standard Entropy of Reactions

  9. Change in Standard Free Energy of Reactions

  10. Maximum and Actual Work Actual work is always less than maximum work due to irrerevsibilities in the system

  11. Free Energy Change in a Chemical Reaction

  12. Effect of Temperature on Spontaneity *The terms high temperature and low temperature are relative. For some reactions, high temperature may mean the room temperature.
