Real Gas Behavior | Fugacity & Equilibrium
Fugacity can be related to the equilibrium constant just like pressure. In this video, we derive an expression for the Kf (fugacity equilibrium constant) using Kp and the fugacity coefficients.

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...

Practice Problem: Solubility Product Constant Calculations
We've learned that there are ionic solids that are insoluble in water, and while for the most part that's accurate, we are bending the truth a little bit. Even compounds that are totally water insoluble will still dissolve a teeny tiny...

The Reaction Quotient
In this video Paul Andersen explains how the reaction quotient is used to determine the progress of a reversible reaction. The reaction quotient (Q) is the ratio of the concentration of products to the concentration of reactants. The...

Making Artificial Earthquakes with a Four-Tonne Steel Ball
In Göttingen, Germany, there's a four-tonne steel ball that can be raised up a 14-metre tower -- and then dropped in less than two seconds, crashing back to earth. It makes tiny, artificial earthquakes: here's why. Thanks to all the team...
