A mixture of CS2(g) and excess O2(g) is placed in a 1.00 L reaction vessel at 100.0 degrees celcius and a pressure of 3.00 atm. A spark causesthe CS2 to ignite, burning it completely, According to the reaction: CS2(g) + 3 O2(g) --> CO2(g) + 2 SO2(g) After the reaction the temerature returns to 100 degrees celcius and the mixture of product gases (CO2, SO2, and untreated O2) is found to have a pressure of 2.40atm. What is the partial pressure of each gas in the product?
