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. Kc for the reaction,
N2, (g)+3H2(g) = 2NH3, (g) is 1.7 * 10^2.
Is the reaction mixture at equilibrium? If not, what is the direction of the net reaction?
