Question

How physisorption and chemisorption are similar?

Answer 1

We can see here that the answer of this question lies in the question itself, so we should think carefully and focus on the terms. And what basically happens in both the processes, then we will be able to find the answer.

Complete step-by-step answer: - Let’s discuss about physisorption: it is found that in this process, physical absorption of some substance into the surface of another material takes place, in which the composition and chemical structure of the surface that the substance has been adsorbed into is not disturbed. The main example of physisorption is seen in the reaction in which alkenes are basically reduced by using a metal catalyst.
- Let’s discuss chemisorption: as we know that it is a type of adsorption, in which one substance adheres into the surface of another material. The main example of chemisorption is rusting of iron.
- As we know that the main similarity between physisorption and chemisorption is that both of them are types of adsorption. That basically involves reactions on the surface of the adsorbent. It is found that both physisorption and chemisorption increases with the increase in surface area.

Note: - We can see here that both of the terms differ vastly. It is found that the surface interaction is one of the only similarities. We should not get confused in both of the terms, as both of them are types of adsorption.
