1.	A reactor is supplied with 5 moles of C4H10, and it undergoes following reactions C4H10 + 4H2O -> 4CO + 9H2 and C4H10 + 6.5O2 -> 4CO2 + 5H2O, if 8 moles of CO2 was produced and 2 moles of C4H10 remains unreacted, what are the number of moles of water produced?(a) 2(b) 5(c) 7.5(d) 10This question was addressed to me in an interview.I'm obligated to ask this question of Processes Involving Multiple Units topic in portion The Chemical Reaction Equation & Stoichometry, Material Balances for Processes Involving Reaction and Multiple Units of Basic Chemical Engineering
Answer» Right ANSWER is (d) 10 To explain: EXTENT of second reaction = (8 – 0)/4 = 2, => moles of water produced = 5*2 = 10.
