Vedclass · Accepted Answer

$ \Delta G = 0, E_{cell} = 0 $

Vedclass · Answer

(A) For a spontaneous electrochemical reaction,the relationship between Gibbs free energy change $(\Delta G)$ and cell potential $(E_{cell})$ is given by the equation: $\Delta G = -nFE_{cell}$.At equilibrium,the net reaction stops,meaning there is no further change in the concentration of reactants and products.At this state,the Gibbs free energy change of the reaction becomes zero,i.e.,$\Delta G = 0$.Substituting $\Delta G = 0$ into the equation $\Delta G = -nFE_{cell}$,we get $0 = -nFE_{cell}$,which implies $E_{cell} = 0$.

At equilibrium,which of the following conditions is satisfied?
