7.12 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, Kc for the reaction is 1.7 × 102. Is the reaction mixture at equilibrium? If not, what is the direction of the net reaction?
The concentration of species are-
We know the formula of
The reaction is not in equilibrium. Since , the equilibrium proceeds in reverse direction.
