Solution: The equilibrium constant Kc for the reaction 2 NOCl(g) → 2 NO(g) + Cl2(g) is 0.51 at a certain temperature. A mixture of NOCl, NO, and Cl2 with concentrations 1.3,1.2, and 0.60 M, respectively, was

Problem

The equilibrium constant Kc for the reaction

2 NOCl(g) → 2 NO(g) + Cl2(g)

is 0.51 at a certain temperature. A mixture of NOCl, NO, and Cl2 with concentrations 1.3,1.2, and 0.60 M, respectively, was introduced into a container at this temperature. Which of the following is true?

1. Cl2(g) is produced until equilibrium is reached.

2. [Cl] = 0.30 M at equilibrium.

3. No apparent reaction takes place. 

4. [NOCl] = [NO] = [Cl] at equilibrium.

5. NOCl(g) is produced until equilibrium is reached.
