The number of incorrect statements from the following is $\displaystyle \_\_\_\_$ A. The electrical work that a reaction can perform at constant pressure and temperature is equal to the reaction Gibbs energy. B. $\displaystyle \mathrm{E}^{\circ}{ }_{\text {cell }}$ is dependent on the pressure. C. $\displaystyle \frac{d E^\theta{ }_{\text {cell }}}{\mathrm{dT}}=\frac{\Delta_{\mathrm{r}} \mathrm{S}^\theta}{\mathrm{nF}}$ D. A cell is operating reversibly if the cell potential is exactly balanced by an opposing source of potential difference.
