At 700 K, the equilibrium constant for the reaction

\mathrm{H_2(g)+I_2(g) \leftrightharpoons 2HI(g)}

K_c = 2.0

. A

2.00\,\text{L}

flask at this temperature contains

0.020\,\text{mol}

\mathrm{H_2}

0.020\,\text{mol}

\mathrm{I_2}

, and

0.030\,\text{mol}

\mathrm{HI}

. Calculate

Q_c

, compare it with

K_c

, and indicate the direction of the net reaction required to achieve equilibrium.
