Problem

The conversion

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

is exothermic and involves a net decrease in the total number of gas molecules. Briefly describe why raising the reaction temperature above

450\,^{\circ}\!\text{C}

can accelerate the production rate yet simultaneously lower the final equilibrium yield of

\mathrm{SO_3}
