At 700 K, the pressure equilibrium constant for the reaction

\mathrm{2SO_2(g)+O_2(g) \leftrightharpoons 2SO_3(g)}

K_p = 3.5 \times 10^{4}

. A vessel at this temperature initially contains

[\mathrm{SO_2}] = 0.10\,\text{M}

[\mathrm{O_2}] = 0.050\,\text{M}

, and

[\mathrm{SO_3}] = 1.2\,\text{M}

. Calculate the value of

K_c

at 700 K, determine

Q_c

for the initial mixture, and state whether the reaction will proceed in the forward or reverse direction to reach equilibrium.
