Question

Write equilibrium constant expressions for Kc for the following processes.

(a) 2CO2(g) ⇌ 2CO(g) + O2(g)
(b) 3O2(g) ⇌ 2O3(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) 2HgO(s) ⇌ 2Hg(l) + O2(g)

Answer 1

(a) Kc = [CO]^2[O2]/[CO2]^2
(b) Kc = [O3]^2/[O2]^3
(c) Kc = [COCl2]/[CO][Cl2]
(d) Kc = [CO][H2]/[H2O][C]
(e) Kc = [H+][HCOO-]/[HCOOH]
(f) Kc = [Hg]^2[O2]/[HgO]^2
