A mixture of CS2 (g) and excess O2 (g) is contained in a 10.0-liter reaction vessel at 100.0°C; the total pressure of the mixture is 3.00 atm. A spark causes the CS2 to ignite, and it burns completely according to the following equation: CS2(g) + 3O2(g)?CO2(g) + 2SO2(g)
The vessel and contents are returned to 100°C and the mixture of product gases (CO2, SO2, and unreacted O2) has a total pressure of 2.40 atm. Determine the partial pressure of each of these gases in the final product mixture.
