The combustion of butane in

\text{O}_2

1

bar and

298 \text{ K}

shows a decrease in free energy equal to

2.75 \times 10^3 \text{ kJ mol}^{-1}

in a fuel cell.

K

and

E^\circ

of fuel cell are : (1)

9.55 \times 10^{482}

1.096 \text{ V}

(2)

9.55

1.096 \text{ V}

(3)

1.023 \times 10^{966}

2.85 \text{ V}

(4)

5.5 \times 10^{484}

0.55 \text{ V}
