Problem

For the gas-phase reaction

\mathrm{N_2O_4(g) \;\rightleftharpoons\; 2\,NO_2(g)}

the equilibrium constant at 298 K is

K_c = 4.6\times10^{-3}

. A sealed 1.00 L flask initially contains

[\mathrm{N_2O_4}]_0 = 0.020\,\text{M}

and

[\mathrm{NO_2}]_0 = 0.100\,\text{M}

. Determine whether the net reaction will proceed in the forward or reverse direction before equilibrium is re-established.
