Write the equilibrium constant expression for K for the following chemical reactions:

(a) N2 (g) + 3 H2 (g) ⇌ 2 NH3 (g)

(b) 2 O3 (g) ⇌ 3 O2 (g)

(c) 2 NO (g) + Cl2 (g) ⇌ 2 NOCl (g)

(d) Ag+(aq) + Cl-(aq) ⇌ AgCl (s)

(e) H2 (g) + I2 (g) ⇌ 2 HI (g)

(f) HF (aq) + H2O (l) ⇌ F-(aq) + H3O+(aq)

(g) SnO2 (s) + 2 CO (g) ⇌ Sn (s) + 2 CO2 (g)
