A simple exothermic A B takes place in the reactor, which is turn cooled by a coolant that flows through jacket around the reactor. The fundamental dependent quantities for the reactor are: A. Total mass of the reacting mixture in the tank B. Mass of chemical A in the reacting mixture C. Total energy of the reacting mixture in the tank
