Kinetic Reaction Control
In this video Paul Andersen explains how a spontaneous process may take either the thermodynamically controlled or the kinetic controlled pathway. If the activation energy determines the path taken then the process is under kinetic...

Making Reactions Go Faster Since the 1700s | Great Minds: Elizabeth Fulhame
The chemical process of catalysis happens in a myriad of places in our modern world - from industry to inside your cells. Our knowledge of catalysis today springs from Elizabeth Fulhame, who over 225 years ago became the first person to...

Multistep Reactions
In this video Paul Andersen explains how an overall chemical reaction is made up of several elementary steps. The stoichiometry of this equation can be predicted but the rate law must be measured. If the elementary steps of the reaction...

Thermodynamics and Energy Diagrams - Crash Course Organic Chemistry
In organic chemistry, different reactions can take place at vastly different speeds. To better understand whether a reaction actually will happen, and how useful that reaction is, we need to understand thermodynamics and kinetics. In...

Radical Reactions Hammonds Postulate - Crash Course Organic Chemistry
Throughout this series we’ve mostly talked about pairs of electrons, but electrons don’t always have a buddy. An atom or group of atoms with a single unpaired electron is called a radical. In this episode of Crash Course Organic...

The Reaction Path
In this video Paul Andersen explains how the reaction path can be described in an energy profile. Enough energy must be added to reach the activation energy required and stress the bonds. Eventually the bonds break and new bonds are...

Gibbs Free Energy
Paul Andersen attempts to explain Gibbs Free Energy. He begins by using three spontaneous reactions to explain how a change in enthalpy, entropy and temperature can affect the free energy of a system. He then applies this concept to...

Activation Energy
In this video Paul Andersen explains how the activation energy is a measure of the amount of energy required for a chemical reaction to occur. Due to the collision theory the activation energy requires proper energy and orientation of...

Catalysts
Paul Andersen explains how catalysts can speed up a reaction without being consumed in the reaction. Catalysts can lower the activation energy of reaction be stabilizing the transition state. They can also create new reaction pathways...
