Textbook Problem

Hydrogenation reactions, processes wherein H2 is added to a molecule, are usually catalyzed. An excellent catalyst is a very finely divided metal suspended in the reaction solvent. Explain why finely divided rhodium, for example, is a much more efficient catalyst than a small block of the metal.

Interpretation Introduction


For the given set of statements it should be identified that whether they are true or false to the given respective given chemical reaction and the false the statements are should be explained.

Concept introduction:

Hydrogenation: The addition of hydrogen to unsaturated compounds to convert into saturated compounds in the presence of catalyst.

Catalyst: The catalyst is a chemical substance that increases the rate of the reaction without participating in the reaction by reducing the activation energy of the reaction.

Collision theory: The rate for the reaction is predicted by using collisions theory. In order to form bond the atoms present in the reactants should collide each other for the bond formation.


The finely divided rhodium metal serves as the best catalyst in increasing the reaction rates since, the surface area of the solid also plays a vital role in reaction rate.

The molecules at the surface of the solid can easily come into contact with the other reactant present in reaction...
