Answer to Question #156246 in General Chemistry for Mohammad Hossain

Question

A mixture of 1.6 mol of PCl5, 0.92 mol of Cl2 and 0.78 mol of PCl3 is introduced into a 20.0 L reaction vessel at 500K. At this temperature, the equilibrium constant Kc for the reaction: PCl5 (g) = PCl3 (g) + Cl2 (g) is 1.8 × 10-3. Is the reaction mixture at equilibrium? If not what is the direction of the net reaction?

Answer 1

The mixture is not at equilibrium

The reaction direction change to backward reaction
