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?

Correct Answer: 0.2
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.
