10 mol/h of benzene (CH) and 20 mol/h of chlorine gas (Cl) are fed to a reactor. Chlorobenzene (C6HCl), di-chlorobenzene (CHCl), and tri-chlorobenzene (CH-C(3) are main products from the process. The exit stream was analyzed and found to contain 1.0 mol/h of Cl, 2.0 mol/h of C6HCl, and 4.0 mol/h of CHCl. The Chlorination of benzene occurs via the following reactions at standard conditions. C6H6+ Cl C6H5Cl + HCl C6H5Cl + Cl C6H4Cl + HCI C6H4Cl2 + Cl C6H3Cl3 + HCl Determine heat transfer amount to/from the process.
