Question

Why transition elements work as catalyst in a chemical reaction?

Answer 1

Hiii machiii ✋.


➡️ Catalysts work by catalytic pathways into the reaction.

➡️ They increase the frequency of collisions between reactants but do not change their physical or chemical properties.

➡️ A catalyst affects the transition state of a reaction by providing the transition state a lower-energy-activation path.

➡️ Transition metals and their compounds function as catalysts either because of their ability to change oxidation state or, in the case of the metals, to adsorb other substances on to their surface and activate them in the process. All this is explored in the main catalysis section.

Answer 2

Catalysts work by catalytic pathways into the reaction. They increase the frequency of collisions between reactants but do not change their physical or chemical properties. ... Acatalyst affects the transition state of a reaction by providing the transitionstate a lower-energy-activation path.
