Question:

Write the expressions for Kc for the following reactions. In each case indicate whether the reaction is homogeneous or heterogeneous.
(a) 2O₃(g) ⇌ 3O₂(g)
(b) Ti(s) + 2 Cl₂(g) Δ TiCl₄(l)
(c) 2C₂H₄(g) + 2 H₂O(g) ⇌ 2C₂H₆(g) + O₂(g)
(d) C(s) + 2H₂(g) ⇌ CH₄(g)
(e) 4HCl(aq) + O₂(g) ⇌ 2H₂O(l) + 2Cl₂(g)
(f) 2C₈H₁₈(l) + 25O₂(g) ⇌ 16CO₂(g) + 18H₂O(g)
(g) 2C₈H₁₈(l) + 25O₂(g) ⇌ 16CO₂(g) + 18H₂O(l)
