JEE MainChemistryElectrochemistryNumerical+4 / −1
The number of incorrect statements from the following is ‾\underline{\hspace{2cm}}​. A. The electrical work that a reaction can perform at constant pressure and temperature is equal to the reaction Gibbs energy. B. Ecell∘\mathrm{E_{cell}^{\circ}}Ecell∘​ cell is dependent on the pressure. C. dEθ cell dT=ΔrSθnF\frac{d E^{\theta} \text { cell }}{\mathrm{dT}}=\frac{\Delta_{\mathrm{r}} \mathrm{S}^{\theta}}{\mathrm{nF}}dTdEθ cell ​=nFΔr​Sθ​ D. A cell is operating reversibly if the cell potential is exactly balanced by an opposing source of potential difference.
