Compounds with carbon-carbon double bonds, such as ethylene, C₂H₁, add hydrogen (H₂) in a reaction called hydrogenation. Calculate the enthalpy change for this reaction, using the following combustion data and Hess's Law. Overall Reaction: 3C₂H₂ +90₂---------> 6CO₂ + 6H₂O 2C₂H+ 70₂.. 2H₂ + 10₂ C₂H₂ + H₂ www. 4CO₂ + 6H₂O 2H₂0 C₂H₂ AH = 1401 KJ AH = 3500 KJ AH = 572 KJ
