Textbook Problem

Hydrogen is produced commercially by the reaction of methane with steam:

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

a. Calculate ∆H° and ∆S° for this reaction (use the data in Appendix 4).

b. What temperatures will favor product formation at standard conditions? Assume ∆H° and ∆S° do not depend on temperature.
