And before we actually calculate anything, the question is, will these sodium ions actually move from this side to this side of that cell membrane? So what we see is, because we have a higher positive charge on this side, these ions will tend to move into that cell. So in this direction. And what that means is this number has to be negative for that to actually be true. Because if we open up the channel, these ions will want to spontaneously move down their electrical gradient from a high electric potential to a low electric potential. And so if we calculate Delta G, we see that the z value is positive one, the F is 96,500 coulombs per mole.
