Problem

In a

5.0\,\text{L}

vessel, the reaction

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

is occurring. Initially the vessel contains

0.60\,\text{mol}

\mathrm{SO_2}

0.40\,\text{mol}

\mathrm{O_2}

, and

0.20\,\text{mol}

\mathrm{SO_3}

. A valve is briefly opened and

0.10\,\text{mol}

\mathrm{SO_3}

is removed while the volume and temperature remain constant. What is the new value of

Q_c

immediately after the removal? a)
