SLO 1.5 - Free Energy and Equilibrium
Bring concepts of thermodynamics together to discuss spontaneity and equilibrium behavior
Back to CHEM 3336
Key Concepts and Skills
- Free Energy: Step through the basic “derivation” (rationale) for the new quantities A and G to describe spontaneity
- Maxwell Relations: Use the maxwell relationships and appropriate gas laws to drill down on specific relationships (internal energy and volume, for example)
- Spontaneity: Use free energy as a criteria for determining spontaneity, compare the respective contributions of entropy and enthalpy
- Equilibrium: Combine equations and relationships from thermodynamics to derive relevant thermodynamic quantities and predict the direction of equilibrium, incorporate the equilibrium constant and reaction quotient
