Question

Equimolar amounts of H₂(g) and CO(g) are mixed in a container at 25 °C. The reaction

Hz(g) + CO(g) + HCHO(g)

takes place. What is the mol fraction of formaldehyde, HCHO, at equilibrium when the total pressure is 10 atm? Assume that you can treat the system at equilibrium as

an ideal gas mixture.

AG (CO,g) = -137.17 kJ/mol

AG°(HCHO,g) = -102.53 kJ/mol
