Calculate the equilibrium constant (Kc) for the given reaction and tell whether equilibrium lies to the left or the right. PCl5 (g) ↔ PCl3 (g) + Cl2 (g)
Equilibrium concentrations are: [PCl5] = 0.25 M, [PCl3] = 9.7 × 10-4 M, and [Cl2] = 3.2 × 10-3 M.
Kc = 2.5 × 10-3; equilibrium lies to the right.
Kc = 5.0 × 10-6; equilibrium lies to the right.
Kc = 3.2 × 10-2; equilibrium lies to the left.
Kc = 1.24 × 10-5; equilibrium lies to the left.
Kc = 1.0 × 10-4; equilibrium lies to the left.

What is the Kc expression for this reaction?
2NO(g) + O2(g) ⇌ 2NO2(g)
Kc = [NO2]2 / ([NO]2 x [O2])
Kc = [NO]2 x [O2] / [NO2]2
Kc = [NO2] / ([NO]2 x [O2])
Kc = [O2] / ([NO]2 x [NO2]2)
Kc = [NO]2 / ([NO2]2 x [O2])

When 0.40 mole of SO2 and 0.60 mole of O2 are placed in an evacuated 1.00–liter flask, the reaction represented below occurs.
2SO2 (g) + O2 (g) ↔ 2SO3 (g)
After the reactants and the product reach equilibrium and the initial temperature is restored, the flask is found to contain 0.30 mole of SO3. Based on these results, the equilibrium constant, Kc, for the reaction is ..................
1.5
2.5

H2(g) + Cl2(g) ⇌ 2HCl(g)
The forward reaction is exothermic. What will happen to the equilibrium if the temperature is increased?
The concentration of H2 will not change.
The equilibrium will shift to the left, favoring H2 and Cl2.

What is the equilibrium expression (Kc) for this reaction?
Fe3O4(s) + 4H2(g) ⇌ 3Fe(s) + 4H2O(g)
Kc = [Fe]3 [H2O]4 / [Fe3O4] [H2]4
Kc = [Fe3O4] [H2]4 / [Fe]3 [H2O]4
Kc = [H2]4 / [Fe]3
Kc = [Fe] [H2O] / [Fe3O4] [H2]
Kc = [H2O]4 / [H2]4
