A mixture of CS2 (g) and excess O2 (g) is contained in a 20.0 liter reaction vessel at 130 degrees celsius; the total pressure of the mixture is 3.0 atm. A spark causes the CS2 to ignite, and it burns completely according to a the following equation.
CS2 (g) + 3O2 (g) ----> CO2 (g) + 2SO2 (g).
The vessel and contents are returned to 130 degree celsius and the mixture of product gases (CO2, SO2, and unreacted O2) has a total pressure of 2.4 atm. Determine the partial pressure of each of these gases in the final product mixture
