I am not able to understand why $E_{cell=0}$.
I went through this answer of the site Electrode Potential at Equilibrium
It says
This eventually comes to a stop when the equilibrium is reached. That is the rate of negative charge build-up is equal to the positive charge. Like you say at this point there is no more drive for the reaction to go one way or the other.
But if rate of negative charge build up is equal to positive charge but we would still have charge separation so why should potential difference be zero?
Like you say at this point there is no more drive for the reaction to go one way or the other.
I know that the Galvanic cells are drove through the Gibbs' energy of redox reaction and I agree that at equilibrium there is no change in Gibbs' energy but we still have charge separation between cathode and anode so why should the potential difference between them be zero ?
I ask my query as a new question here because answerer to the linked question has been inactive for long time.
