1. What is Gibbs Free Energy?
2. What is the equation for Gibbs Free energy
3. Explain how the equation for Gibbs Free can be used as a criterion for whether or not a chemical reaction will be spontaneous.
4. Give an example of a specific chemical reaction that has specific values for delta H and delta S and for T and determine whether or not the reaction will be spontaneous.
