In the production of metallic manganese, 10 kg of manganese oxide, Mn3O4, are heated in an electric furnace with 3.0 kg of amorphous carbon (coke). The resulting products are found to contain 4.8 kg of manganese metal and 2.6 kg of manganous oxide, MnO, as slag. The remainder of the products consists of unconverted charge and carbon monoxide gas. Calculate the standard heat of reaction of this process for the entire furnace charge. Heats of formation at 25°C are as follows: Mn304 = - 331.4 k cal/gm mole MnO = - 92.0 kcal /gm mole Mn = 0kcal/gm mole CO= -26.416 kcal/gm mole Coke +2.6 kcal/gm mole Atomic weight of manganese = 55 In the production of metallic manganese, 10 kg of manganese oxide, Mn3O4, are heated in an electric furnace with 3.0 kg of amorphous carbon (coke).
