12. Predict the direction of the equilibrium shift when temperature is decreased in the following reactions:

a. C₂H₂ (g) + H₂O (g) ? CH₃CHO (g) [?H = -151 kJ/mol]

b. CH₃CH₂OH (l) + O₂ (g) ? CH₃CH₂O (g) + H₂O (g) [?H = exothermic]

c. 2 CH₃CHO (g) ? 2 C₂H₄ (g) + O₂ (g) [?H = endothermic]

13. Consider the following endothermic reaction for the production of hydrogen gas in a rigid container:

CH₄(g) + H₂O(g) ? CO(g) + 3 H₂(g)

How will the yield of hydrogen change if the equilibrium is disturbed by:

a. Adding a catalyst.

b. Increasing the pressure.

c. Decreasing the temperature.

d. Adding inert argon gas.

e. Increasing the temperature.
