Frequent question: Which of the following is adsorbed to maximum extent on charcoal?

Which of the following is adsorbed to a maximum extent?

Answer-(4) Xe gas is adsorbed to maximum extent.

Which among the following gases will be adsorbed most easily on charcoal?

Ne gets easily absorbed over charcoal than He.

Which among the following is adsorbed greatly activated charcoal?

Water vapours. Stronger the intermolecular forces, easier to liquify, more strogly adsorbed.

Which of the following gas is adsorbed to a greater extent?

C.A gas having lowest critical temperature. D.A gas having highest critical pressure. Hint: Gases that liquefy easily have greater intermolecular forces and hence are adsorbed on a solid surface to greater extent. etc.

Which gas is adsorbed to maximum?

The gases, which are easily liquifiable such as NH3,CO2,HCl etc. are adsorbed to greater extent than permanent gases like O2,H2, N2,He etc.

What is positive and negative adsorption?

In case of adsorption by solids from the solutions, mostly the solute is adsorbed on the surface of the solid adsorbent so that the concentration of solute on the surface of the adsorbent is greater than in the bulk. This is known as positive adsorption. … This is called negative adsorption.

Which gas absorbs least?

Answer: (d) Lesser the value of critical temperature of gases lesser will be the extent of adsorption. Here H2 has lowest value of critical temperature, i.e., 33. Hence, hydrogen gas shows least adsorption on a definite amount of charcoal.

Which gas is observed strongly by charcoal?

The gas that can be strongly adsorbed by charcoal is B) NH3.

The reason behind this is that NH3 is easily liquifiable. Charcoal strongly absorbs those compounds that are easily liquifiable, which is the case with ammonia or NH3. The gas can be easily liquefied because of more surface area.

Which gas is adsorbed maximum Activated Carbon?

Gases with higher critical temperatures are readily adsorbed. Thus 1gram of activated charcoal adsorbs more SO2 (critical temp. 630K) than methane (critical temp 190K) which is still more than dhiydrogen (critical temperature 33K).

Which of the following is adsorbed more on 1g of activated charcoal?

Thus, 1g of activated charcoal adsorbs more sulphur dioxide (critical temperature 630K), than methane (critical temperature 190K) which is still more than 4.5 mL of dihydrogen (critical temperature 33K).

Which is adsorbed in minimum amount by the activated charcoal?

Here , hydrogen has the minimum critical temperature, (-240∘C) hence, is adsorbed in minimum amount.

Which adsorption is multilayered?

In multilayer adsorption the adsorption space accommodates more than one layer of molecules and not all adsorbed molecules are in contact with the surface layer of the adsorbent. ) for both monolayer and multilayer adsorption is defined as the ratio of the amount of adsorbed substance (see §§1.1.
