Question: is e cell 0 at equilibrium?
Answer: The Equation above indicates that the electrical potential of a cell depends upon the reaction quotient Q of the reaction. As the redox reaction proceeds, reactants are consumed, and thus concentration of reactants decreases. ... At equilibrium, the reaction quotient Q=Keq. Also, at equilibrium, ΔG=0 and ΔG=−nFE, so E=0.
