5. Liquid hydrazine, N2H4 is a rocket fuel. It combusts in oxygen gas to form nitrogen gas and
water. Calculate the enthalpy change for the combustion of hydrazine.
2NH3 (2) + 3N20g) → 4N22) + 3H2O w
N2O(g) + 3 H2 (2) → N2H4(1) + H20 (1)
2NH3(2) + ½ 02 (g) → N2H41) + H2O (1)
H2 (e) + ½ O2 (2) → H2O (1)

AH = - 1010kJ
+ H2O (1)
AH= -317 kJ
AH = - 143 kJ
AH=-286 kJ
Ans: -623 kJ
6. Calculate AH for the reaction C2H4 (g) + H2 (g) C2H6 (g), from the following data.
C2H4 (g) + 3 O2 (g)2 CO2 (g) + 2 H2O (1)
C2H6 (g) + 7/2 02 (g)2 CO2 (g) +3 H2O (1)
H2 (g) + 1/2 O2 (g) H2O (1)
AH =-1411, kJ/mol
AH = -1560. kJ/mol
AH = -285.8 kJ/mol
Ans: -136.8kJ
