Problem

6.12 A mixture of 1.57 mol of

N_2

, 1.92 mol of

H_2

and 8.13 mol of

NH_3

is introduced into a 20 L reaction vessel at 500 K. At this temperature, the equilibrium constant,

K_c

for the reaction

N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g)

1.7 \times 10^2

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