Expert Answer:

The change of alkene to alkane is an addition reaction and it is carried out by addition of hydrogen to alkenes.The reaction is known as hydrogenation.
 
When ethene and hydrogen are passed over finely divided catalysts such as platinum or palladium at ordinary temperature or nickel at 200oC, two atoms of hydrogen molecule are added to the unsaturated molecule, which thus becomes a saturated one i.e., ethane
