A. The electrical work that a reaction can perform at constant pressure and temperature is equal to the reaction Gibbs energy.

B.   $E_{cell}^{\circ}$ is dependent on the pressure.

C.   $\frac{d E^{θ} cell}{d T} = \frac{Δ_{r} S^{θ}}{n F}$

D.  A cell is operating reversibly if the cell potential is exactly balanced by an opposing source of potential difference. [2023]

Ans.
(1)

$E_{cell}^{0}$ is defined at constant temperature and 1 bar pressure.
