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 is included along with a walkthrough of several calculations.
Paul Andersen defines the equilibrium constant (K) and explains how it can …
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 reactants. If the K value is less than one the reaction will move to the left and if the K value is greater than one the reaction will move to the right.

In this video Paul Andersen explains how disturbances to a reversible reaction at equilibrium affect the equilibrium constant and the reaction quotient. For example if the concentration is changed the reaction will move to reestablish the equilibrium constant. If the temperature is changed a new equilibrium constant will be established.

We visit a fluorine expert to finally show you this incredibly reactive element in action. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.
Paul Andersen explains how thermodynamic and equilibrium reasoning can be related through …
Paul Andersen explains how thermodynamic and equilibrium reasoning can be related through changes in free energy and the equilibrium constant. When the delta G is negative the reaction shifts to the right or favors products. When the delta G is positive the reaction shifts to the left or favors reactants. In biological systems exergonic reactions (like cellular respiration) can be linked to endergonic reactions (like the production of ATP).

In this video Paul Andersen explains how gases differ from the other phases of matter. An ideal gas is a model that allows scientists to predict the movement of gas under varying pressure, temperature and volume. A description of both the kinetic molecular theory and Maxwell-Boltzmann Distribution are included.

In this video Paul Andersen explains how energy can be transferred from warmer objects to colder objects through heat. Temperature is a measure of the average kinetic energy of the particles in a substance. When two objects are in contact collisions between the particles will transfer energy from the warmer object in the form of heat.
