For a given reaction reactor is supplied with a feed of composition 46% C3H7O4, 44% O2 and 10% N2 and if 50% of the limiting reagent conversion takes place. 4C3H7O4 + 11O2 → 12CO2 + 14H2O 7. What is the percentage of O2 in the product?

Correct Answer: 18
Assume that 100 moles of feed is present in the reactor and do the material balance for each, Percentage of O2 = 18%.
