On roasting, iron pyrite, FeS,, converts quantitatively into Fe₂O3. 4FeS₂ + 110₂ → 2Fe₂O3 + 8S0₂ A sample of FeS, is roasted completely in a closed vessel, by twice the stoichiometric amount of air (0₂ = 20%, N, = 80%, by volume) needed. What is the volume percent of SO, gas in the final gaseous mixture present in the vessel ? (1) 800 -% 19 800 -% 25 -% 3 (3) 400 59

Answer:
The process of eudiometry is used to calculate the volume of the various reacting gases present in a closed vessel. A spark is made and the change in volume or pressure is noted depending on the conditions mentioned.
