Question
10. Compounds with carbon-carbon double bonds, such as ethylene, C,H4. add
hydrogen (H,) in a reaction called hydrogenation. Calculate the enthalpy
change for this reaction, using the following combustion data and Hess's Law.
Overall Reaction:
C,H, + H,
C,H,
3C,H, + 90,
6CO, + 6H,0
ΔΗ=1401 KJ
2C,H, + 70,
4CO, + 6H,0
AH = 3500 KJ
2H, + 10,
2H,0
ΔΗ 572 KJ
