Chapter 19, Problem 6E

The theoretical $E_{\text{col}}^{°}$ for the methane-oxygen fuel cell is 1.06 V. What is $E°$ for the reduction half-cell ${\text{CO}}_{\text{2}}\left(\text{g}\right)+8{\text{H}}^{+}\left(\text{aq}\right)+8{\text{e}}^{-}\to {\text{CH}}_{\text{4}}\left(\text{g}\right)+2{\text{H}}_{\text{2}}\text{O}\left(\text{l}\right)$ ?
[Hint: Refer to cell reaction (19.27).]
