← ScienceWhich consequence results when hydrogen gas is reacted with a heated nickel catalyst?
A)Alkene hydrogenation causes alkane formation✓
B)Dehydrogenation leads to catalyst poisoning
C)Steam reforming generates syngas
D)Hydrogen diffusion causes metal embrittlement
💡 Explanation
Alkene hydrogenation forms an alkane because the nickel catalyzes the addition of hydrogen atoms using surface adsorption. Therefore, saturation occurs with alkane formation, rather than other products, because of adsorbed hydrogen’s high reactivity in such environments.
