Chapter 8, Problem 8.32E

The thermite reaction can act as the basis of an electrochemical cell:

$\text{2Al}\left(\text{s}\right)+{\text{Fe}}_{\text{2}}{\text{O}}_{\text{3}}\left(\text{s}\right)\to {\text{2Al}}_{\text{2}}{\text{O}}_{\text{3}}\left(\text{s}\right)+2\text{Fe}\left(\text{s}\right)$

Estimate the electrochemical potential of this reaction at $1700°\text{C}$ if $E°$ is $1.699\text{V}$. You will need to look up thermodynamic data in Appendix 2.
