Chlorine is produced by the following reaction: 4HCl (g) + O2 (g) 2H2O (g) + 2Cl2 (g) The feed stream to the reactor consists of 60 mol % HCl, 36 mol % O2, and 4 mol % N2, and it enters the reactor at 550C. If the conversion of HCl is 75% and if the process is isothermal at 550C, how much heat must be transferred to or from the reactor per mole of the entering gas mixture? Assume ideal gas
