Khan Academy: Calculating Equilibrium Constant Kp Using Partial Pressures

How much pressure is exerted by the mixture of gases in a scuba tank? Introduce pupils to Dalton's Law of Partial Pressure and vapor pressure in the video sure to interest the class. The video also reminds viewers that gases are not...

Figuring out the partial pressures of various gases in a container is the focus of this chemistry video. Sal sets up a problem where a balloon is filled with three different types of gases: oxygen, hydrogen, and nitrogen. The goal is to...

Why do reversible reactions just keep going and going? Savvy solution chemists learn how to influence reactants and products at equilibrium through a video lesson. Topics include the conditions that affect equilibrium, reaction rates,...

Reversible reactions, equilibrium, and the equilibrium constant K. Learn how to calculate K, and how to use K to determine if a reaction strongly favors products or reactants at equilibrium.

Walk through an example problem for calculating the equilibrium constant K using the standard cell potential. [9:37]

Ignoring the solvent or the solid state molecules when calculating the equilibrium constant. [9:22]

At equilibrium, the rate of the forward reaction is equal to the rate of the backward reaction. Learn how to calculate the equilibrium constant K, the reaction quotient Q, and equilibrium concentrations. [12:01]

Find the relationship between standard cell potential and equilibrium constant K. [5:18]

A probabilistic look at how molecules react to develop the intuition behind the equilibrium constant formula. [12:52]
