PHC413 Adsorption

Adsorption is a bulk phenomenon.

• True

• False

Physical adsorption involves Van der Waals forces.

• True

• False

Chemical adsorptions permit only the formation of a monolayer af adsorbates on the adsorbent.

• True

• False

Chemical adsorption is easily reversible.

• True

• False

Adsorption is an endothermic process.

• True

• False

Complex structures are more easily adsorbed than simpler ones.

• True

• False

Adsorption processes proceed more rapidly at higher temperatures.

• True

• False

Increasing the surface area of the adsorbent increases the adsorption.

• True

• False

Adsorption isotherm is the process by which the adsorbate is adsorbed on the adsorbent as a function of its pressure (if gas) or concentration (if liquid) at constant temperature.

• True

• False

Freundlich isotherm provided a theoretical relationship between the amount of gas adsorbed by a unit mass of solid adsorbent and pressure at a particular temperature. 

• True

• False
