The reaction between ethylene (C2H4) and hydrogen bromide (HBr) to form ethyl bromide (C2H5Br) is carried out in a continuous reactor. The product stream is analyzed and found to contain 51.7 mol% C2H5Br and 17.3 mol% HBr. The feed of the reactor contains only C2H4 and HBr. Calculate the fractional conversion of the limiting reactant. If the molar flow rate of the feed stream is 165 mol/s, what is the extent of the reaction?
