A mixture of gaseous carbon disulfide and excess oxygen is placed in a 9.50 L reaction vessel at 100.0°C and a pressure of 3.25 bar. A spark causes the carbon disulfide to ignite. The complete consumption of carbon disulfide leads to the production of gaseous carbon dioxide and sulfur dioxide. After the reaction, the system is allowed to re-equilibrate at 100.0°C, and the pressure of the mixture of three gases is found to have a pressure of 2.75 bar. What is the partial pressure of each gas in the product mixture?
