This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
Which of the following is not not a quality of the process known as chemisorption? It cannot be undone in any way.
Which of the following does not NOT describe chemisorption?
The process of chemisorption causes an increase in temperature because it is an exothermic one and the temperature continues to rise throughout the process. While temperatures are low, the chemisorption process moves at a glacial pace, but when pressure is raised, the process picks up speed significantly. Hence, chemisorption does not result in the formation of multimolecular layers. Because of this, the option D is the one that should be chosen.
Which of these is NOT a hallmark of the process known as chemisorption?
The process of chemisorption causes an increase in temperature because it is an exothermic one and the temperature continues to rise throughout the process. While temperatures are low, the chemisorption process moves at a glacial pace, but when pressure is raised, the process picks up speed significantly. Since the process of chemisorption involves the production of chemical bonds, the enthalpy is relatively large.
The chemisorption phenomena does not exhibit which of the following characteristics?
It cannot be undone in any way.
Which of the following is not an accurate statement regarding chemisorption?
The adsorption process is referred to as chemical adsorption if the chemical forces involved in it are responsible for holding the gas molecules to the surface of the adsorbent. The process of chemisorption cannot be reversed.
Which of the following is not not a quality of the process known as chemisorption?
We found 15 questions connected to this topic.
In regards to chemisorption, which of the following statements is accurate?
The creation of a monomolecular layer is a step in the chemisorption process. The process is irreversible in the natural world and requires a high enthalpy of adsorption, which is equal to between 50 and 400 kJ/mol. The higher the pressure, the more advantageous it is for it to exist, although it is unaffected by lower pressures. As a result, one could argue that chemisorption is unaffected by the surrounding pressure.
What are some of the qualities that physisorption possesses?
Adsorption or Physisorption Referring to the Physical Process
The following is a list of the features of physisorption: Because any gas can have its molecules adsorb onto a surface, there is no specificity. It has been found that highly liquifiable gases are physically adsorbed with a stronger force than other gases. It is reliant not just on temperature but also pressure, and it can go either way in the natural world.
Which property of the adsorption process is incorrect?
The enthalpy and entropy changes that occur during adsorption are both on the negative side.
Which of the following is an example of anything that can be absorbed?
Answer in its entirety: > An example of adsorption would be water sitting on silica gel. On the surface of the silica gel, water molecules are still there.
What exactly is meant by the term “proper physical adsorption”?
The process of physical adsorption is analogous to the transformation of gases into liquids and is dependent on the physical force of attraction, also known as the van der Waals force, that exists between the molecules of the adsorbate and the solid adsorbent. Every gas has the potential to become adsorbed on any surface because there is no chemical specificity in physical adsorption….
Why is the process of chemisorption in nature so specific?
Due to the fact that the molecules are retained on the solid surface by a chemical link, chemisorption is a very particular process in the natural world. For eg. oxygen is adsorbed on metals due to oxide production and likewise hydrogen gets adsorbed on metals due to hydride formation. … Because of this, chemisorption is a very particular process because they can only be adsorbed on metal.
Which one of these is not an attribute of the Physisorption process?
Only when there is a bond formed between the molecules of the adsorbent and the adsorbate does it take place. A high enthalpy of adsorption, on the scale of 40 to 400 kJ/mol, is exhibited by this substance. It creates a layer consisting of single molecules. Thus, property C does not fall under the category of chemisorption.
What exactly do you mean when you say chemisorption?
The process of chemical adsorption known as chemisorption is triggered by a reaction that takes place on an exposed surface. This reaction results in the formation of an electronic link between the surface and the adsorbate. In the course of the chemical reaction, a separate chemical species is produced on the surface of the adsorbent, which is what ultimately leads to the formation of the bond.
Which one of the following cannot be said to be a property of matter?
Matter does not have inertia.
Is chemisorption a process that can be reversed or one that cannot?
The process of chemisorption is one that cannot be reversed and favors higher pressure.
Which of the following does not not qualify as a solid characteristic?
Option D is nothing from the previous options. After the study of the several potential possibilities, we have arrived at the conclusion that the attributes of solid include a distinct state, rigidity, and volume. This option is the definitive response to this question because all of the other choices—options A, B, and C—are characteristics of solids.
What are some illustrations of the concept of absorption?
The process through which one item becomes a part of another object is referred to as absorption. Another way to think of absorption is as the act of something soaking, either literally or figuratively. A good illustration of absorption is the process of cleaning up a milk spill using a paper towel.
Is there a water-absorption reaction when ammonia comes into contact with it?
Ammonia, which has a higher binding energy (adsorption strength) than water, takes the place of water at unsaturated Cu2+ metal centers when water is present. This occurs because ammonia has a higher adsorption strength than water. The connection between the metal and the ammonia is strengthened by the hydrogen bonds between the water and the ammonia due to cooperative interactions.
Which one of the following serves as an illustration of an absorption indicator?
One example of an absorption indicator is known as eosin.
In the process of adsorption, which of these characteristics is accurate?
The process of adsorption happens naturally. When the temperature rises, there is a corresponding increase in adsorption. The process of adsorption on solids can be reversed.
Which of the following is NOT a feature of the process of adsorption?
A direct result of surface energy is a process known as adsorption. The nature of the bonding between the atoms can be attributed to either physisorption or chemisorption, both of which are characteristics of a weak van der Waals force or covalent bonding, respectively. Electrostatic attraction is another possible cause of this phenomenon.
Which of the following descriptions does not accurately describe the process of physical adsorption?
Which of the following descriptions of the adsorption process does not accurately describe physical adsorption? Solution: When the temperature drops, the amount of physical adsorption that can take place increases because easily liquifiable gases are able to adsorb more. Thus, the assertion in option A is false.
Please explain the concept of physisorption with an example.
Adsorption of gases such as hydrogen, nitrogen, and others at lower temperatures on the surface of an adsorbent such as charcoal is an illustration of physisorption in action. The amount of surface area available to an adsorbent is a critical factor in physisorption… For instance, porous solids and finely split metals both have a significant amount of surface area.
Why does physisorption include multiple layers but chemisorption only involves one?
Answer: the layers of physical adsorption are multiple, whereas the layers of chemisorption are only one. The inter-molecular attractive interactions that exist between the adsorbate and the adsorbent are responsible for the physical adsorption process. Chemisorption, on the other hand, involves the formation of chemical bonds between the molecules of the adsorbate and the adsorbent.
