Using standard thermodynamic data from Appendix L of your text, calculate the equilibrium constant at 298 K for the following chemical reaction:
CO(g) + H2O(l) CO2(g) + H2(g).

Answer:

CO(g) + H2O(l) CO2(g) + H2(g) G = (394.359 + 0) (137.168 237.15) = 20.04 kJ/mol G = RT ln K 20.04 = (8.3145 x 103)(298) ln K
ln K = K = 3290
