Under what condition E cell is zero?
Explanation: Under what condition is E∘cell=0 or ΔrG=0.
Solution : Both can be equal to zero when the reaction is is in a state of equilibrium..
Why is equilibrium at Ecell 0?
Because at equilibrium the net loss of electron is equal to net gain of electron and potential diffrence is zero so E=O.
Why is e Cell 0 in a concentration cell?
Concentration cells consist of anode and cathode compartments that are identical except for the concentrations of the reactant. Because ΔG = 0 at equilibrium, the measured potential of a concentration cell is zero at equilibrium (the concentrations are equal).
Is E cell always positive?
Re: Positive or negative Ecell In order for delta G to be negative, which indicates that the reaction is a spontaneous one, E cell must be positive. For electrolytic cells, which are reactions that occur only with the input of an external energy source, E cell is negative because they are nonspontaneous.
Can e Not cell be zero?
No, E°cell or △G°r for cell reaction can never be zero. E° is never zero hence,△G° will also be not equal to zero.
What is the difference between Ecell and E cell?
E cell means electrode potential of a cell. E0 cell means standard electrode potential means electrode potential measured at 1 atmosphere pressure, 1 molar solution at 25° C.
