Re: E vs E naught
E is not under standard conditions, E naught is. Standard conditions are at 1 atm, 1 mols of each solution, and at 25 degrees Celsius. Note that when calculating K in one of the equations, E is equal to 0, not E naught.

Re: E vs E naught
º means "under standard conditions," which indicates 1atm, 1 mol, and 25ºc (298K)
so Eº refers to potential difference specifically under these conditions, while E does not specify the conditions.

Re: E vs E naught
E naught is a lot like G naught from thermodynamics. Its the value of E at standard conditions. At nonstandard conditions (E), we have to convert using an equation.

Re: E vs E naught
Eo is measured at 1 atm, 298 K, and 1 M. It is used to find cell potential under nonstandard condition, E, with .

Re: E vs E naught
E naught is the energy under standard conditions, whereas E is just the general energy. In order to find the energy not under standard conditions, you must use E naught

Re: E vs E naught
E naught is E under standard conditions, just as deltaG naught is deltaG under standard conditions.

Re: E vs E naught
Eº is E under standard conditions which are 1M and 1atm, similar to standard gibbs free energy Gº which is also under standard conditions.

Re: E vs E naught
E naught signifies standard conditions (1 M, 25 C, 1 atm) and does not get affected by change in concentrations, unlike E.

Re: E vs E naught
E° is just E under standard conditions, which are 1 M, 1 atm, & at 25°C (or 298 K).

Re: E vs E naught
E naught is in standard conditions meaning 1 atm , 298k but E is not that is why you have to find the new temperature and different pressure when you use the E equation.

E naught
What is the point of balancing the half reactions and writing out the cell reactions when solving for E naught when you can just use the equations that plugs in the two values and you subtract them. As long as you know what the anode and cathode is... what is the point of writing it all out?

Re: E vs E naught
E naught represents the standard reduction potential of a redox reaction (think 25 degrees Celsius, 1 atm, etc.). E represents the reduction potential at a given condition, so it changes based on temp, pressure, and moles of electrons.

Re: E vs E naught
The e naught signifies reduction potential at standard conditions, whereas e is reduction potential with other conditions.

Re: E vs E naught
E naught is the cell potential at standard conditions which would be 1.0 M or 1 atm. E would be the cell potential at all the other conditions.

Re: E vs E naught
E naught is basically E but in standard conditions, so think Celsius, Kelvin, atm, etc...

Re: E vs E naught
To add on to what everyone already said, it's the same thing with Gibbs free energy we did. G naught is under standard conditions and G is under any conditions. hopefully relating the two will help us remember!

Re: E vs E naught
The E naught value is the value of the cell potential under standard conditions, whereas E is just the potential of the cell.

Re: E vs E naught
E naught is under standard conditions, and is fixed! Sapling gives us a list of E naught values I believe

Re: E vs E naught
Hi there! E naught is going to be our cell potential under standard conditions, while just regular E by itself is going to be cell potential under non-standard conditions. Hope this helps!

Re: E vs E naught
E naught is under standard condition and does NOT depend on how many times the reaction has occurred.

Re: E vs E naught
The relationship between E and E naught is the same as the other variables such as G and G naught; E naught is simply E of the reaction at ideal conditions.
