Worksheet #1: Equilibrium Constants Write the expression for the equilibrium constant Keq for the reaction below: 1) N2(g) + 3H2(g) ⇔ 2NH3(g) 2) 2KClO3(s) ⇔ 2KCl(s) + 3O2(g) 3) H2O(l) ⇔ H+(aq) + OH-­‐(aq) 4) 2CO(g) + O2(g) ⇔ 2CO2(g) 5) Li2CO3(s) ⇔ 2Li+(aq) + CO3-­‐2(aq) Using the equilibrium constant expressions you determined in column 1, calculate the value of Keq when the following concentrations are present: [NH3] = 0.0100 M; [N2] = 0.0200 M; [H2] = 0.0200 [O2] = 0.0500 M; [KCl] = 0.00250 M; [KClO3] = 2.00 M [H+] = 1 x 10-­‐8 M; [OH-­‐] = 1 x 10-­‐6 M; [H2O] = 1 x 10-­‐14 M, [CO] = 2.0 M; [O2] = 1.5 M; [CO2] = 3.0 M [Li+] = 0.20 M; [CO3-­‐2] = 0.10 M; [Li2CO3] = 6.0 M
