6. Which of the following is true about the equation G=-vF&, where & is the emf of a given cell? A. This equation is the key connection between electrical measurements on the one hand and thermodynamic properties on the other. B. When &>0 it indicates that the forward reaction is spontaneous. C. When &=0, then G would be zero, indicating that the cell reaction is at equilibrium. D. All A, B, and C are true. E. Only A and C are true.
