a mixture of CS2(g) and excess O2(g) is placed in a 10.0L reaction vessel at 100.0 Celsius and pressure of 3.oo atm. A spark causes the CS2(g) to ignite, burning it completely. After reaction, temp returns to 100.0 celsius and mixture of product gases is found to have a pressure of 2.40atm. what is the partial pressure of each gas in the product mixture?
