Write equilibrium constant expressions for Kc, and for Kp, if applicable, for the following processes: (a) 2 CO2 (g) <=> 2 CO (g) + O2 (g)
(b) 3 O2 (g) <=> 2 O3 (g)
(c) CO (g) + Cl2 (g) <=> COCl2 (g)
(d) H2O (g) + C (s) <=> CO (g) + H2 (g)
(e) HCOOH (aq) <=> H^+ (aq) + HCOO^- (aq)
(f) 2 HgO (s) <=> 2 Hg (l) + O2 (g)
