    Mean Weak
In summary, the research paper suggests that weak chemisorption of silver with olefins actually makes it a more effective separator for olefins and paraffins. This is because the weak binding allows for better separation through a technique called chemisorption. This may seem counterintuitive, but it is due to the way solid materials and catalysts interact with vapor molecules.

TL;DR Summary
How come silver having a weak chemisorption of olefins means it is a good olefin/paraffin separator?
I am reading a research paper that says weak chemisorption of silver with olefins basically means more effective olefin/paraffin separation. If silver weakly binds to olefins, wouldn't that make a lousy separator?

The opposite is true taken in its proper content. You see...
In general solid materials have "weak" surface energy distribution sites (that is probably what is confusing you), where vapor molecules or gas can adhere to or bonded with the help of a catalyst commonly heterogeneous catalyst. Through a technique using the chemical absorption phenomena.
"Chemisorption".
But I should have asked what research paper are you referring to?
In any event. I hope this helps it's a good read.

Given the information this is probably a stretch.The material used to bond to silver is more than likely,but I could be wrong, vaporized using the sputter technique in a vacuum.
 

What does weak chemisorption mean?

Weak chemisorption refers to the relatively weak bonding between a molecule and a surface. It occurs when the interaction between the molecule and the surface is primarily due to weak van der Waals forces, rather than strong covalent bonds.

What is the difference between weak chemisorption and strong chemisorption?

The main difference between weak chemisorption and strong chemisorption is the strength of the bonding between the molecule and the surface. In weak chemisorption, the bonding is primarily due to weak van der Waals forces, while in strong chemisorption, the bonding is primarily due to strong covalent bonds.

What factors contribute to weak chemisorption?

Weak chemisorption can be influenced by several factors, including the nature of the molecule and surface, temperature, and the presence of other molecules or substances that may compete for bonding sites on the surface.

How does weak chemisorption affect surface reactions?

Weak chemisorption can impact surface reactions by decreasing the rate of reaction or hindering the formation of strong chemical bonds between the surface and the reacting molecules. It can also affect the selectivity of reactions, as weakly adsorbed molecules may be easily displaced by other molecules.

Can weak chemisorption be beneficial in certain situations?

Yes, weak chemisorption can be beneficial in certain situations. For example, it can allow for reversible adsorption of molecules on a surface, which can be useful in catalysis or separation processes. Additionally, weak chemisorption can help prevent unwanted reactions or surface contamination by weakly adsorbing impurities.
