A reaction mixture for the combustion of SO_2 was prepared by opening a stopcockconnecting two separate chambers, one having a volume of 2.125 litres filled with SO_2 at 0.75 atm and the other having 1.5 litres volume filled with oxygen at 0.50 atm, both gases were at 80^@C.(i) What were the mole fractions of SO_2 and O_2in the mixture, and the total pressure?(ii) If the mixture was passed over a catalyst that promoted the formation of SO_3and was then returned to the original two connected vessels, what were the mole fractions in the final mixture and what was the final total pressure? Assume that the conversion of SO_2 is complete to the extent of the availability of O_2
