This chemistry video tutorial discusses the relationship between cell potential and gibbs free energy. It contains plenty of examples and chemistry practice problems. It discusses the signs of the potential energy and delta G in determining if a reaction is spontaneous or nonspontaneous. The system is in equilibrium whenever delta G and E is equal to zero. This video discusses Faraday's constant which relates the electric charge to moles of electrons per mole of substance. 1 volt is 1 Joule per coulomb. voltage is a measure of electrical potential energy per unit charge. delta G represents the maximum amount of electrical work that can be performed by a reaction. This tutorial contains problems where you have to find the value of n in order to use it in the equation delta G = -nFE. To find it, you need to balance the half reactions and make sure the moles of electrons are the same using the least common multiple rule. In addition, you need to calculate the cell potential of the net reaction using the standard reduction potential of the half reactions. This lesson is basically a section in electrochemistry.
