What is Gibbs Free Energy?
Think about the energy related to work.
How is the equilibrium constant Kp related to Gibbs free energy?
Recall the formula provided.
What does a negative standard free energy change indicate?
Think about spontaneity in terms of energy state.
The relationship ΔG° = -RT ln Kp implies that:
Recall the specific formulas discussed.
A reaction has a Kp of 50. What is ΔG° at 298 K?
Use proper units for R and remember the properties of natural log.
If two reactants are mixed and their initial concentrations lead to a Kp of 0.02, discuss the spontaneous nature of the reaction.
Relate back to the definitions of Kp and degree of spontaneity.
