Using the Heat of Reaction (Hrxn) to Find Amounts Organic hydrogenation reactions, in which H2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. In the simplest case, ethene (C2H4) and H2 form ethane (C2H6). If 163 kJ is given off per mole of C2H4 reacting, how much heat is released when 14.9 kg of C2H6 forms? kJ?
