Problem

At 310 K, the reaction Fe

^{3+}

(aq) + e

^{-}

→ Fe

^{2+}

(aq) has a standard cell potential of

E^{\circ}=+0.15\,\text{V}

and involves

n=1

electron. Using

R=8.314\,\text{J mol}^{-1}\,\text{K}^{-1}

and

F=9.6485\times10^{4}\,\text{C mol}^{-1}

, what is the value of the equilibrium constant

K

at 310 K? a)

3.6\times10^{-3}

b)

2.7\times10^{2}

c)

1.1\times10^{1}

d)

5.6\times10^{5}
