Adsorption Process Quiz

What is adsorption?

• A process where a gas or liquid solute accumulates on the surface of a solid or liquid

• A process where a gas or liquid solute dissolves in a liquid

• A process where a solid or liquid dissolves in a gas

• A process where a solid or liquid accumulates on the surface of a gas

What is the principle of adsorption process?

• Transfer of certain components of a fluid phase to the surface of a solid adsorbent

• Transfer of the entire fluid phase to the surface of a solid adsorbent

• Transfer of the solid adsorbent to the fluid phase

• Transfer of the fluid phase to the solid adsorbent

Which of the following is a property of adsorbents?

• Rigidity

• Density

• Transparency

• Selectivity

What is the difference between absorption and adsorption?

• Absorption is favored by low temperature, while adsorption is not affected by temperature

• Absorption is exothermic, while adsorption is endothermic

• Absorption is a surface phenomenon, while adsorption is a bulk phenomenon

• Absorption is a bulk phenomenon, while adsorption is a surface phenomenon

What is the type of adsorption where the force of attraction between the adsorbate and adsorbent is very weak?

• Mechanical adsorption

• Biological adsorption

• Chemical adsorption

• Physical adsorption

Which substance is known as adsorbate in the adsorption process?

• Liquid adsorbent

• Solid adsorbate

• Solid adsorbent

• Gas or liquid solute

What is the purpose of using adsorbents in the form of spherical pellets or rods?

• To have high surface area and large pore diameters

• To have low surface area and high thermal stability

• To have low thermal stability and large pore diameters

• To have high abrasion resistance and small pore diameters

Which factor affects adsorption?

• Shape of adsorbent

• Nature of adsorbate and adsorbent

• Color of adsorbent

• Size of adsorbate particles

What is the purpose of batch adsorber in the adsorption process?

• To extract various components from a gaseous mixture or liquid

• To cool down the adsorbate solution

• To mix different adsorbents together

• To heat the adsorbent material

What does the adsorption isotherm graph represent?

• The concentration of the adsorbate as a function of its pressure or temperature at constant amount of adsorbent

• The pressure of the adsorbent as a function of its concentration at constant temperature

• The amount of adsorbate on the adsorbent as a function of its pressure or concentration at constant temperature

• The temperature of the adsorbent as a function of its pressure or concentration at constant amount of adsorbate
