A 1.50 L reaction vessel contains a gaseous mixture of 2.1 mol NOCl, 0.52 mol NO, and 0.21 mol Cl2. The vessel was heated to 400°C until the system attained equilibrium. If Kc is 0.035 at this temperature, to which direction did the reaction proceed to attain equilibrium?
2NOCl (g) ↽−−⇀ 2NO (g) + Cl2 (g)
The reaction shifted to the left
