Calculate the ratio of the syn-periplanar conformation to the anti-periplanar conformation that produces the trans alkene. Can we use this ratio of the energies to explain the predominance of the trans alkene

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 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
