Question
Final answer should be in KJ. Show all work on a separate piece of paper and submit work in part B. Clearly label question # and answer. Failure to show work will result in a zero
for this question.
Determine AH/kJ for the following reaction using the listed enthalpies of
reaction:
N2H4(1) + 2 H2O2(g) →N2(g) + 4 H2O(1)
N2H4 (1) + 02 (g) → N2 (g) + 2 H20 (1)
H2 (g) + 1/2 02 (g) → H20 (1)
H2 (g) + 02(g) → H2O2 (1)
Â#º/kJ
AH°/kJ
AH°/kJ = -187.8 kJ
= -622.3 kJ
= -285.8 kJ
Type your answer.
