2) Chlorine is produced by the reaction: 4HCI (g)+0,(g) 2H2O(g) + 2C1,(g) The feed stream to the reactor consists of HCl and air in an equimolar mixture, and it enters the reactor at 550 C. If the conversion of HCl is 75%, what is the maximum temperature that can be reached? Assume that heat is only supplied initially to preheat the feed stream to 550 C, and no further heat is added to the reactor
