Equilibrium in Electrochemical Cells
Equilibrium in electrochemical cells is the point at which the rate of the forward reaction equals the rate of the reverse reaction. At this point, the cell potential (Ecell) becomes zero, and the equilibrium constant (K) becomes equal to the electrode potential (Eo).
Explanation
When an electrochemical cell is at equilibrium, the concentration of the reactants and products is constant. At this point, the cell potential (Ecell) becomes zero because there is no net flow of electrons. This means that the rate of the forward reaction is equal to the rate of the reverse reaction.
The equilibrium constant (K) is a measure of the extent to which a reaction proceeds towards products. At equilibrium, K becomes equal to the electrode potential (Eo). The electrode potential is the measure of the tendency of an electrode to gain or lose electrons. It is a measure of the relative strength of the oxidizing or reducing agent.
Therefore, at equilibrium, the cell potential (Ecell) becomes zero, and the equilibrium constant (K) becomes equal to the electrode potential (Eo). This means that the reaction has reached a state of balance, and there is no net flow of electrons.
Conclusion
In summary, at equilibrium in electrochemical cells, the cell potential (Ecell) becomes zero, and the equilibrium constant (K) becomes equal to the electrode potential (Eo). This is the point at which the rate of the forward reaction equals the rate of the reverse reaction, and the reaction has reached a state of balance.
