A mixture of ferric oxide (Fe_(2)O_(3)) and Al is used as a solid rocket fuel which reacts to give Al_(2)O_(3) and Fe . No other reactants and products are involved . On complete reaction of 1 mole of Fe_(2)O_(3), 200 units of energy is released. (a) Write a balance reaction representing the above change. (b) What should be the ratio of masses of Fe_(2)O_(3) and Al taken so that maximum energy per unit of fuel is released. (c) What would be energy released if 16 kg of Fe_(2)O_(3) reacts with 2.7 kg of Al.
