Which expression correctly relates the standard free-energy change

\Delta G^\circ

to the standard cell potential

E^\circ_{\text{cell}}

, the amount of electrons transferred

n

, and Faraday’s constant

F

? (a)

\Delta G^\circ = -2.303\, nF E^\circ_{\text{cell}}

(b)

\Delta G^\circ = n F E^\circ_{\text{cell}}

(c)

\Delta G^\circ = -n F E^\circ_{\text{cell}}

(d)

\Delta G^\circ = -\dfrac{F E^\circ_{\text{cell}}}{n}
