A packed bed reactor with fresh catalyst is started to operate at 600 K. To keep the reaction rate constant, the reactor feed temperature is increased over time. When the temperature rises to 800 K after four weeks, the reactor is stopped to reactivate the catalyst. At any given moment the reactor is isothermal. Find the activity of the catayst at the end of four weeks. Reaction rate for the fresh catalyst is: -r, = kC, k= ke -7200/T
