How do we use use faradays constant in the equation for Gibbs free energy?

### Re: Faradays Constant

Gibbs free energy= -nFE
Where n stands for the number of molecules of that compound.
F is Faradays constant.
E is the cell potential for the entire cell.

### Re: Faradays Constant

Faradays constant is the "F" in the equation. It's units will help cancel out the others to leave you with units of energy!

### Re: Faradays Constant

Faradays constant = 96485 C/mol.

It's given on the formula sheet so you don't have to memorize it

### Re: Faradays Constant

Just to add on, charge = moles of electrons transferred times Faraday = nF
