Question:

Does the reaction in Exercise 70 or that in Exercise 71 produce more energy per kilogram of reactant mixture (stoichiometric amounts)?
Reaction of exercise 70
3Al(s) + 3NH4ClO4(s) → Al2O3(s) + AlCl3(s) + 3NO(g) + 6H2O(g)
Reaction of exercise 71
5N2O4(l) + 4N2H3CH3(l) → 12H2O(g) + 9N2(g) + 4CO2(g)
