Hydrogenation of carbon double bonds C=C (i.e. adding a hydrogen on each carbon atom and thus reducing the double bond into a single bond: H-C-C-H) is a very common process in organic and polymer chemistry. Using the data from the following table, calculate the Hreaction when ethylene C2H4 is reduced into ethane according to the reaction below:C2H4(g) + H2(g) --> C2H6(g)
