A reactor is supplied with 2 streams both at same rates, one has pure Cl2, and another has pure C2H6, if the product has 20% C2H5Cl and 80% HCl, what is the ratio of rate of feed and rate of product?(a) 0.2(b) 0.5(c) 2(d) 5I had been asked this question during an interview.I'd like to ask this question from Element Material Balances in section The Chemical Reaction Equation & Stoichometry, Material Balances for Processes Involving Reaction and Multiple Units of Basic Chemical Engineering

Answer»

Right CHOICE is (a) 0.2

The explanation is: The reaction is C2H6 + Cl2 -> C2H5Cl + HCl, Let the rate of feed and products be F and P RESPECTIVELY. ELEMENT balances, C: F(2) = 0.2P(2), => F/P = 0.2.
