Chapter 3, Problem 74E

The major industrial source of hydrogen gas is by the following reaction:

${\text{CH}}_{\text{4}}\left(g\right){\text{ + H}}_{\text{2}}\text{O}\left(g\right)\to \text{CO}\left(g\right){\text{ + 3H}}_{\text{2}}\left(g\right)$

Use bond energies to predict ∆E for this reaction.
