Khan Academy: Standard Cell Potential and the Equilibrium Constant

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,...

Understand standard cell potential and the equilibrium constant. [4:37]

Finding the relationship between standard cell potential and equilibrium constant K. [5:21]

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.

Know how to use a table of standard reduction potentials to calculate standard cell potential. Identify trends in oxidizing and reducing agent strength. [9:03]

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

In the following video 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...

The relationship between standard Gibbs free energy change and the equilibrium constant K. Calculating K when you know the standard free energy of reaction. [10:45]

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]
