## Extra Help For Chapter 16

This is a great introduction to the concept of equilibrium, establishing equilibrium, and the equilibrium constant. You don’t need to watch after 7:27, because at that point, he goes into more depth than this course does.

This video shows you how to get the equation of the equilibrium constant.

This video shows you how to get the value of the equilibrium constant. He says that K doesn’t have units, but it really does, as shown in your text.

This video shows you how to determine the concentration of a chemical if you are given the equilibrium constant and the concentrations of the other chemicals in the equation.

This video shows you how to determine which way a reaction must shift to reach equilibrium. He uses the symbol “Qc” to represent the equation for K.

This video explains how salt melts ice.

This video explains how Le Chatelier’s Principle works.

This video explains how to figure out the direction an equilibrium will shift when it is stressed.

This video explains acid and base ionization constants. You don’t have to watch after 6:00, because at that point, she goes into detail that the course doesn’t cover.
