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

N₂(g) + 3H₂(g) ⇌ 2NH₃(g) is 1.7 x 10^-2 

Is this reaction at equilibrium? if not. what is the direction of net rection?

Answer 1

The reaction is: N₂(g) + 3H₂(g) ⇌ 2NH₃(g)

The equilibrium constant (Kr) for the reaction = 1.7 x 10^-2

As Q_C ≠ K_C; this means that the reaction is not in a state of equilibrium.
