A cell reaction would be spontaneous if the cell potential and $\Delta_{\mathrm{r}} G$ are respectively :

A cell reaction would be spontaneous if the cell potential and $\Delta_{\mathrm{r}} G$ are respectively :
  1. positive and negative
  2. negative, negative
  3. zero, zero
  4. positive, zero

Solution

For spontaneous $\Delta_{\mathrm{r}} \mathrm{G}^{\circ}=-\mathrm{nFE}^{\circ} < 0$
$\therefore \mathrm{E}^{\circ}>0$
