Chapter 13, Problem 66E

Use data from Appendix D to determine (a) ${\Delta }_{t}H°,{\Delta }_{t}S°$ , and ${\Delta }_{t}G°$ at 298 K and (b) K at 875 K for the water gas shift reaction, used commercially to produce ${\text{H}}_{\text{2}}\left(\text{g}\right)\text{:CO}\left(\text{g}\right){\text{+H}}_{\text{2}}\text{O}\left(\text{g}\right)\rightleftharpoons {\text{CO}}_{\text{2}}\left(\text{g}\right){\text{+H}}_{\text{2}}\left(\text{g}\right)$ .

[Hint: Assume that ${\Delta }_{t}H°$ and ${\Delta }_{t}S°$ are essentially unchanged in this temperature interval.]
