For the reaction

$$N_2 + 3H_2 \rightleftharpoons 2NH_3$$

with $K_c = 6 \times 10^{-1}$ at $500^{\circ}C$, predict the direction in which the system will shift to attain equilibrium when concentrations of $H_2$, $N_2$, and $NH_3$ are $1.0 \times 10^{-2}$ M, $1.0 \times 10^{-3}$ M, and $1.0 \times 10^{-3}$ M respectively.
