Question

The reaction of liquid hydrogen peroxide, H2O2, with liquid hydrazine has also
been suggested as a source of energy for small rockets. Find out ΔHrxn for
this reaction and compare the usefulness of the reaction.
2H2O2(l) + N2H4(l) → N2(g) + 4H2O(g)
ΔHf values: H2O2(l) = –187.8 kJ/mol
N2H4(l) = 50.6 jJ/mol
N2(g) = 0
H2O(g) = –238.8 kJ/mol
