16. Chemical Equilibrium

Provide K expression for the reverse of the following reaction:

Fe₂O₃(s) + 3 H₂(g) ⇌ 2 Fe(s) + 3 H₂O(g)

Which of the reactions is likely to produce more O₂ at equilibrium at 25°C?

Consider the reaction A(g) ⇌ B(g) + C(g), with k_forward of 5.7 x 10^–2 and k_reverse of 3.8 x 10^–4. Which would be greater at equilibrium, partial pressure of A or partial pressures of B and C?

When glucose, a sugar, reacts fully with oxygen, carbon dioxide and water are produced according to the equation: C₆H₁₂O₆(s) + 6 O₂(g) ⟺ 6 CO₂(g) + 6 

H₂O(l) Write the expression for Kc for this reaction.

For a particular reaction K = 98000. What can be said about this reaction?
