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]
