Problem: The reaction between propane and hydrogen chloride to form propyl chloride and hydrogen is carried out in a continuous reactor. The product stream is analyzed and found to contain 27.45 mole% C3H7Cl, 27.45 mole % H2 and 14.6% HCl. The feed to the reactor contains only propane and hydrogen chloride. Calculate the fractional conversion of the limiting reactant and the percentage by which the other reactant is in excess. If the molar flow rate of the feed stream is 290 mol/s, what is the extent of reaction? (Give its numerical value and its units.) Explanation: So, we've seen that we don't know how to find fractional conversion yet because we haven't found the amounts of the two different reactants that are entering the reactor. Fractional conversion and percent excess both require that you know the amounts of all reactants entering the reactor so that you can determine which one is the limiting reactant. So, at this point, we can't solve for any of the answers directly. We'll need to do some other work first... You don't need a code number from this step because we can't do anything yet... |
