A 10 liter flask at 298 K contains a gaseous mixture of O2 and CO2 at 1 atmosphere. Which statement is true for the partial pressures of O2 and CO2 if 0.2 mole of O2 is present in the flask? (Given the universal gas constant R = 0.082 L∙atm/K∙mol)
A.
The partial pressures of O2 and CO2 are 0.48 atmospheres and 0.52 atmospheres respectively.
B.
The partial pressures of O2 and CO2 are 0.52 atmospheres and 0.48 atmospheres respectively.
C.
The partial pressures of both O2 and CO2 are 0.50 atmospheres.
D.
The partial pressures of both gases are 1 atmosphere.
E.
The partial pressures of O2 and CO2 are 0.2 atmospheres and 0.8 atmospheres respectively.
