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...

Enthalpy: Crash Course Chemistry
Energy is like the bestest best friend ever and yet, most of the time we take it for granted. Hank feels bad for our friend and wants us to learn more about it so that we can understand what it's trying to tell us - like that any bond...

Using Gibbs Free Energy
In this video Paul Andersen explains how you can use the Gibbs Free Energy equation to determine if a process is spontaneous or not spontaneous. If the _G is less than zero the process is spontaneous. If the _G is greater than zero the...

Entropy: Embrace the Chaos! Crash Course Chemistry
Life is chaos and the universe tends toward disorder. But why? If you think about it, there are only a few ways for things to be arranged in an organized manner, but there are nearly infinite other ways for those same things to be...

Energy Changing Processes
In this video Paul Andersen explains how energy can enter and leave a system. The amount of energy a substance can receive through heating or lose through cooling is measured using the specific heat capacity. Phase changing energy from...

Spontaneous Processes
In this video Paul Andersen discriminates between spontaneous (or thermodynamically favored) processes and those that are not spontaneous. A spontaneous process requires no external energy source. If the enthalpy change in a reaction...

Calorimetry
In this video Paul Andersen describes the history of calorimetry and explains how it can be used to measure energy changes in a system. The specific heat of water is well established and so as a system releases or absorbs energy from a...

TED-ED: What triggers a chemical reaction? - Kareem Jarrah
Chemicals are in everything we see, and the reactions between them can look like anything from rust on a spoon to an explosion on your stovetop. But why do these reactions happen in the first place? Kareem Jarrah answers this question by...

Enthalpy of Reaction
In this video Paul Andersen explains how the enthalpy of a reaction can be released in an exothermic or consumed in an endothermic reaction. According to Hess's law if the reaction is reversed the sign of the enthalpy of reaction is also...
