WebSo the value 58 mV comes not out of thin air but from the terms in equation 3. Please don't panic. If you remember the Nernst potential as equation 1, you'll be fine, but you should remember that the number is 61 mV (and not 58 mV) at mammalian body temperature. Nevertheless, there are textbooks that give the Nernst equation as shown in equation 2. WebNov 13, 2024 · E = E° − RT nFlnQ ⏟ applicable at all temperatures. This is the Nernst equation that relates the cell potential to the standard potential and to the activities of the electroactive species. Notice that the cell potential will be the same as E° only if Q is unity.
