Chemical Kinetics #4 -- Reaction pathways, Activation Energy, and Kinetic Reaction Control

Watch the following videos to help understand reaction pathways and activation energy.  The third video helps to explain how catalysts work and the difference between kinetics and thermodynamics.

Chemical Kinetics #3 -- Rate Limiting Step

Watch the following video to help understand what the rate determining step of a reaction is and how it can be used to determine a reaction mechanism.

Chemical Kinetics #2 -- Rate Laws and Rate Constants

Watch the following videos to help understand how to create a rate law for a reaction and how to determine the rate constant from a rate law.

Chemical Kinetics #1 -- Overview and Ways to affect speed of reaction

Watch the following videos to get a good overview of the topics in the Kinetics unit and the specific of how to affect the rate of reactions.

Beer's Law and Spectrophotometry

Watch the first video to help you understand how light can be used as a measurement and analysis tool in chemistry -- pay extra attention to the part about the Beer-Lambert Law.





Watch the second video to get an idea about the next lab we will be doing, Spectrophotometric Determination of Concentration, or Beer's Law.  We will be using a spectrophotometer just like this teacher does in our lab, although ours will be larger and older.

Intermolecular Forces #2: Vapor Pressure, Normal Boiling Point, Triple Point

Watch the following videos to help visualize and understand the concepts of vapor pressure, Pressure-Temperature Phase Diagrams, and the Triple Point -- as all are related to Intermolecular Forces.

Intermolecular Forces #1: IMF's in general and how they work in liquids

Watch the following videos to help you better understand the origins of intermolecular attractive forces, the different types of IMF's and their relative strengths, and how these IMF's create the properties of liquids.
