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

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)
