adsorbtion

[smurphy1D]

Does adsorbtion only occur for heterogeneous catalysts?

[chrisleung-2J]

I believe so, as adsorption refers to the physical contact of reactants with the surface of a catalyst in a different state. If the catalyst were homogeneous I believe that we wouldn't consider the contact to be adsorption since there is no such contact between substances of different physical states.

To add on, adsorption is defined as reactants on the surface of the catalyst. For this to occur, I believe it is implied that the catalyst will have to be solid, so that there can be a surface for the reactants to rest on and react with. If it were a homogenous catalyst, the complex would likely form in a solution.

Hope this helped!

Yes, I believe so. Adsorption is when reactants sit on the surface of a catalyst versus absorption, where you can think of water soaking into a sponge (reactant breaching surface of the catalyst).

[John Liang 2I]

yes, because homogenous catalysts would absorb being in the same state of matter. the example used in class was that the catalytic converter was solid while gas sits on top of it rather than being absorbed. it's adsorbed. hope this helps

Yea its reactants sitting on the surface

Since adsorption refers to molecules staying on the surface of a solid, it only occurs in heterogeneous catalysts. The only exception I could think of is if the reactants of the reaction that are adsorbed are also solid, but I assume this is very rare.
