4FeS2 + 11O2 ----> 2Fe2O3 + 8SO2
A production error leads to the sulfide being placed in a 750L vessel with insufficient oxygen. The partial pressure of O2 is 0.44atm and the total pressure is initially 1.05atm with the balance N2. The reaction is run until 85% of the O2 is consumed and the vessel is cooled to its initial temperature. What is the total pressure and partial pressure of each gas in the vessel.
