Solution: The equilibrium constant is 0.0900 at 25ºC for the reaction H2O(g) + Cl2O(g) ⇌ 2HOCl(g)For which of the following sets of conditions is the system at equilibrium? For those that are not at equilibrium

Problem

The equilibrium constant is 0.0900 at 25ºC for the reaction 

H2O(g) + Cl2O(g) ⇌ 2HOCl(g)

For which of the following sets of conditions is the system at equilibrium? For those that are not at equilibrium, in which direction will the system shift? 

a. A 1.0-L flask contains 1.0 mole of HOCl, 0.10 mole of Cl 2O, and 0.10 mole of H2O.

b. A 2.0-L flask contains 0.084 mole of HOCl, 0.080 mole of Cl 2O, and 0.98 mole of H2O. 

c. A 3.0-L flask contains 0.25 mole of HOCl, 0.0010 mole of Cl 2O, and 0.56 mole of H2O.
