Problem

Initially, a 5.00 L container at a fixed temperature holds 0.800 mol of

\mathrm{SO_2(g)}

and 0.500 mol of

\mathrm{O_2(g)}

. After the system reaches equilibrium, 0.300 mol of

\mathrm{SO_3(g)}

is present. What is the value of

K_{c}

for the reaction

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

under these conditions? a)
