Now, for example, if we have 1 mol in our cell, that means we multiply 1 mol times f.
So 1 mol times this guy gives us the most cancel, and we simply get our charge. So n times f is our charge. Now, this equation becomes important when we build a relationship between our cell voltage and gear spree energy. So let's see what the relationship is. So, let's finally examine and see what the relationship is between cell voltage and changing gear free energy. Well, we see that changing gear's free energy is equal to negative of electrical work done.
