1. Consider the following reaction where Kc = 1.29×10-2 at 600 K. COCl2(g) CO(g) + Cl2(g)

A reaction mixture was found to contain 9.87×10-2 moles of COCl2(g), 2.19×10-2 moles of CO(g), and 3.79×10-2 moles of Cl2(g), in a 1.00 liter container.

Is the reaction at equilibrium?
If not, what direction must it run in order to reach equilibrium?

The reaction quotient, Qc, equals
The reaction:
A. must run in the forward direction to reach equilibrium.
B. must run in the reverse direction to reach equilibrium.
C. is at equilibrium.
