Patents, Novelty, and Trolls: Crash Course Intellectual Property
This week, Stan teaches you about patents. It turns out, they're patently complicated! So, patents have some similarity to copyright, in that they grant a limited monopoly to people who invent things. The key difference in patents and...

Elementary Reactions
In this video Paul Andersen explains that elementary reactions are steps within a larger reaction mechanism. Colliding molecules require sufficient energy and proper orientation to break bonds and form new bonds. A unimolecular reaction...

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 is...

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...

Equilibrium
In this video Paul Andersen explains how equilibrium is achieved in a reversible reaction. When the rate of the forward reaction is equal to the rate of the reverse reaction the system is at equilibrium. Graphical analysis of equilibrium...

The Equilibrium Constant
In this video Paul Andersen defines the equilibrium constant (K) and explains how it can be calculated in various reversible reactions. The equilibrium constant is a ratio of the concentration of the products to the concentration of the...

Stoichiometry
In this video Paul Andersen explains how stoichiometry can be used to quantify differences in chemical reactions. The coefficients in a balanced chemical equation express the mole proportions in that reaction. These values can be used to...

Impulse
In this video Paul Andersen defines impulse as the product of the force applied and the time over which the force is applied. The impulse of an object is equivalent to the change in momentum of the object. Several problems related to...

Electromagnetic Induction
In this video Paul Andersen explains how electromagnetic induction occurs when the magnetic flux of an object changes. The magnetic flux is product of the surface area perpendicular to the magnetic field and the magnetic field strength....
