1.	A reactor is supplied with 5 moles of KNO3 and some H2SO4, if the extent of reaction is 2, how many moles of H2SO4 were supplied?(a) 1(b) 2(c) 5(d) Cannot be determinedThis question was addressed to me during an interview for a job.Origin of the question is Species Material Balances topic in division The Chemical Reaction Equation & Stoichometry, Material Balances for Processes Involving Reaction and Multiple Units of Basic Chemical Engineering
Answer» The CORRECT OPTION is (d) Cannot be determined To explain: SINCE the final moles of H2SO4 are not GIVEN, initial moles cannot be determined.
