Hydrogenation reactions are used to add hydrogen across double bonds in hydrocarbons and other organic compounds.
Use average bond energies to calculate DELTA Hrxn for the following hydrogenation reaction:
H2C==CH2(g) + H2(g)-->H3C--CH3(g)
2)Use standard enthalpies of formation to calculate DELTA Hrxn for the following reaction.
CH4(g)+2O(g)--->CO2(g)+2H2O(g)
