Problem

Sulfur trioxide is produced in the gas phase according to

2\,\text{SO}_2\,(g) + \text{O}_2\,(g) \rightleftharpoons 2\,\text{SO}_3\,(g)

. At a given temperature the system is at equilibrium with partial pressures

P_{\text{SO}_2}=0.40\,\text{atm}

P_{\text{O}_2}=0.20\,\text{atm}

, and

P_{\text{SO}_3}=0.60\,\text{atm}

. The volume of the container is then compressed to one-half its original value, and the temperature is held constant. After the system reaches a new equilibrium, what is the partial pressure of

\text{SO}_3

closest to? a)

1.60\ \text{atm}

1.32\ \text{atm}

0.96\ \text{atm}

1.20\ \text{atm}
