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. And we see that this quantity, so Delta V is so we have to use V, not milliv. And so it's negative zero point 45. And we multiply these out and we get a negative quantity.
