Question

A mixture of 1.57 mol of N₂, 1.92 mol of H₂ and 8.13 mol of NH₃ is introduced into a 20 L reaction vessel at 500 K. At this temperature, the equilibrium constant, K_c for the reaction 

Is the reaction mixture at equilibrium? If not, what is the direction of the net reaction

Answer 1

The given reaction is: 

Now, reaction quotient Qc is: 

Since, Q_c ≠ K_c, the reaction mixture is not at equilibrium. 

Again, Q_c > K_c . Hence, the reaction will proceed in the reverse direction.
