4FeS2 + 11O2 -> 2Fe2O3 + 8SO2, what is the extent of reaction if 512 grams of SO2 is produced?
A. 1
B. 2
C. 3
D. 4
I got this question during an online exam.
Origin of the question is Stoichiometry Applications Terminology topic in section The Chemical Reaction Equation & Stoichometry, Material Balances for Processes Involving Reaction and Multiple Units of Basic Chemical Engineering
The correct option is A. 1
The explanation: Moles of SO2 = 512/64 = 8, => Extent of reaction = (8 – 0)/8 = 1.
