The concept of chemical equilibrium is very important for the student to grasp. It is very important to understand that we are talking about a dynamic equilibrium, not a static equilibrium. Molecules and atoms are still moving around, but overall they have reached an equilibrium (like in A + B --> C, there are always the same number of A's, B's, and C's on "their" side of the arrow but they are not the same A's, B's, and C's. You will learn how to write a reaction quotient and an equilibrium constant and you will learn how they are different. You will learn how to determine the equilibrium constants under various conditions and you will learn how to manipulate the equilibrium constants. You will learn what disturbs a chemical equilibrium and the effect of temperature on the equilibrium composition and therefore the equilibrium constant. You will learn about other perturbations on the system that may change the equilibrium constant (Le Chatelier's principle).

Here is an overview that I provided for CHEM 1151 on the same topics of Chemical Equilibrium. It is a series of slides with me talking about the topics and you will need a Real Player to see/hear the presentation.
