Vedclass · Answer

(D) For a spontaneous process,the Gibbs free energy change $(\Delta G)$ must be negative $(\Delta G For an electrochemical cell,the relationship between Gibbs free energy and cell potential $(E_{cell})$ is given by $\Delta G = -nFE_{cell}$.For $\Delta G$ to be negative,$E_{cell}$ must be positive $(E_{cell} > 0)$.Therefore,the correct condition for the spontaneity of a cell is $\Delta G = -ve$ and $E_{cell} = +ve$.

For the spontaneity of a cell,which of the following is correct?
