Interactive Activity-The Relationship among Eocell, Keq, and Gibbs Free Energy lectrochemical cell the potential In an electrochemical cell, the potential difference between two electrodes under standard conditions is known as the standard cell potential (Ecell). The standard cell potential be used to identify the overall ten can be used to identify the overall tendency of a redox reaction to occur spontaneously. The spontaneity of a reaction is identified using the Gibbs free energy G. AG" is related to Edell. Ecell and , are also related to equilibrium constant Keq of the reaction. Select the image to explore the activity that shows how all, Keq, and Go are related to each other. Kec eq E cell

Explanation / Answer

Eocell = -RTlnKeq

For the above given cell,

Eocell = 0.337 - (-0.257) = 0.594 V

Feed values,

0.594 = - (8.314 x 298) lnKeq

Keq = 1.000
