Answer:

During the catalytic hydrogenation of ethyne, ethene is formed first which in the next step is further reduced to ethane. In this reaction, the heat of hydrogenation of the first π bond is higher than that of the second. ... Reduction of alkynes with sodium in liquid ammonia (solvated electrons) yields trans alkenes.
