Big Idea 6: Any Bond or intermolecular attraction that can be formed can be broken. These two processes are in a dynamic competition, sensitive to initial conditions and external disterbances.
Enduring understanding 6A: Chemical equilibrium is a dynamic reversible state in which rates of opposing processes are equal.
Enduring Understanding 6B: Systems at equilibrium are responsive to external stresses, with the response leading to a change in the composition of the system.
Enduring Understanding 6C: Chemical equilibrium plays an important role in acid-base chemistry and solubility.
- Acid base: See Acid base chapter.
- Solubility equilibrium: See Ksp
Enduring Understanding 6D: The equilibirum constant is related to temperature and the difference in Gibbs free energy between reactants and products. (See Thermodynamics)
In the previous chapter (solubility equilibrium) you learned about how to set up an equilibrium expression and how to convert between equilibrium constant and equilibrium concentration. This chapter is going to extend what you already have learned. In this chapter we will introduce the equilibrium constant Kc and Kp. The subscript only indicates the type of reaction being used. It does not have any affect on the logistics of equilibrium. We will also be introducing the concept of Le Chateliers principle.
