It is a quantity that has a constant value in nature. Some constants have units, while others do not. While the physical value of a constant does not depend on its units, obviously changing the units is associated with a numerical change.
WebTo calculate the free energy change (ΔG) of a cell, you can use the following equation: ΔG = -nFΔE. where: ΔG is the free energy change of the reaction, measured in joules (J) n is the number of moles of electrons transferred in the reaction. F is the Faraday constant, which is equal to 96,485 coulombs per mole of electrons. WebKey Concepts and Summary. Electrical work (w ele) is the negative of the product of the total charge (Q) and the cell potential (E cell).The total charge can be calculated as the number of moles of electrons (n) times the Faraday constant (F = 96,485 C/mol e −).Electrical work is the maximum work that the system can produce and so is equal to …
