Given at 25°C:

2Cl2(g) + 2H2O(g) ⇄ 4HCl(g) + O2(g) Kp = 3.2x10-14

Write the equilibrium constant expressions for Kc and Kp and calculate their values for

the reaction

writing in the following forms:

a. 4HCl(g) + O2(g) ⇄ 2Cl2(g) + 2H2O(g)

b. 2HCl(g) + ½O2(g) ⇄ Cl2(g) + H2O(g)

c. Cl2(g) + H2O(g) ⇄ 2HCl(g) + ½O2(g)

d. 4Cl2(g) + 4H2O(g) ⇄ 8HCl(g) + 2O2(g)

e. ½Cl2(g) + ½H2O(g) ⇄ HCl(g) + ¼O2(g)

Bromine chloride, BrCl, is a reddish covalent gas with properties similar to those of

Cl2, may eventually replace Cl2 as a water disinfectant. One mole of chlorine and one mole

of bromine are enclosed in a 5.0L flask and allowed to reach equilibrium at a certain

temperature.

Cl2(g) + Br2(g) ⇄ 2BrCl(g) Kc = 4.7x10-2

We place 0.500mole CO, 0.500mole H2O, 0.500mole CO2, and 0.500mol H2 in a 1.00L

container under the conditions in problem #8. What will be the equilibrium concentrations

of all species present?
