Unit 13 General & Solubility Equilibria
While we know chemical equilbrium is no longer the topic of Question 1 of the FR, we DO know that is still important enough to have its own Big Idea! (Big Idea 6) We have also learned that it is best to learn Equilbrium in two parts: Unit 13 - General Equilibrium: Kc, Kp and Ksp & Unit 14 - Acid-Base Equilibrium and Buffers.

Le Chatelier’s Principle

Le Chatelier's Principle - Professor Dave Explains (4:08) [here] If a system is at equilibrium, and we do something to it, it will shift in a particular way. It is quite easy to predict the behavior of equilibria if we know about Le Chatelier's principle and three simple situations!
RICE Tables
Equilibrium Equations: Crash Course Chemistry #29
Hank shows you that, while it may seem like the Universe is messing with us, equilibrium isn't a cosmic trick. Here, he shows you how to calculate equilibrium constant & conditions of reactions and use RICE tables all with some very easy, not-so-scary math. ICE Tables made EASY! ~Justin Mueller (7:53) [here]

Fritz Haber - Great Minds
~SciShow (9:40) Brilliant and heartless Fritz Haber, a great mind who is considered "the father chemical warfare," but who also made discoveries and innovations that helped lead to the Green Revolution which is credited with preventing the starvation of over a billion people.

Learning Outcomes After studying this chapter, you should be able to:
- Explain what is meant by chemical equilibrium and how it relates to reactions rates.
- Write the equilibrium-constant expression for any reaction.
- Given the value of Kc convert to Kp and vice versa.
- Relate the magnitude of an equilibrium constant to the relative amounts of reactants and products present in an equilibrium mixture.
- Manipulate the equilibrium constant to reflect changes in the chemical equation.
- Write the equilibrium-constant expression for a heterogeneous reaction.
- Calculate an equilibrium constant from concentration measurements.
- Predict the direction of a reaction given the equilibrium constant and the concentrations of reactants and products.
- Calculate the equilibrium concentrations given the equilibrium constant and all but one equilibrium concentration.
- Calculate equilibrium concentrations, given the equilibrium constant and the starting concentrations.
- Use Le Chatelier’s principle to predict how changing the concentrations, volume, or temperature of a system at equilibrium affects the equilibrium position.
