7. Kc = [NO]2/[NO3–]2[H+]8[Cu2+]3
8. Kc = [CO2][NH3]2/[NH2COONH4]
9. Kc = [Cl2]^2[H2O]^2/[HCl]^4[O2]
10. Kc = [PbO]^2[SO2]/[PbS]^2[O2]^3
11. Kc = [F2]½[I2]½/ [IF]
12. Kc = [Ni(CO)4]/[Ni][CO]4
13. Kc = [NH3][H2S]/[NH4HS]
14. Kc = [POCl3]^10/[P4O10][PCl5]^6
Write an equilibrium constant expression for each of the following chemical equations. Remember that only (aq) and (g) are kept in the equilibrium constant expression. Do your work on paper and then compare it with my answers.
7.
2NO3– (aq) + 8H+(aq) + 3Cu(s) ⇌ 2NO(g) + 3Cu2+(aq) + 4H2O(l)
8.
NH2COONH4(g) ⇌ CO2(g) + 2NH3(g)
9.
4HCl(g) + O2(g) ⇌ 2Cl2(g) + 2H2O(g)
10.
2PbS(s) + 3O2(g) ⇌ 2PbO(s) + 2SO2(g)
11.
IF(s) ⇌ ½F2(g) + ½I2(g)
12.
Ni(s) + 4CO(g) ⇌ Ni(CO)4(g)
13.
NH4HS(g) ⇌ NH3(g) + H2S(g)
14.
P4O10(g) + 6PCl5(g) ⇌ 10POCl3(g)
