1.	A reactor supplied with CO2 and H2O, the product contains H2O and H2CO3, if the rate of H2O is 10 mole, what is the rate of products?(a) 5 mole(b) 10 mole(c) 15 mole(d) 20 moleThis question was addressed to me in exam.Asked question is from Element Material Balances topic in chapter The Chemical Reaction Equation & Stoichometry, Material Balances for Processes Involving Reaction and Multiple Units of Basic Chemical Engineering
Answer» The correct option is (b) 10 MOLE For explanation I would SAY: The reaction is CO2 + H2O -> H2CO3. Let the RATE of products be P, and the FRACTION of H2CO3 in products be x, material balances, H: 10(2) = xP(2) + (1 – x)P(2), => P = 10 mole.
