Which of the following is greatly adsorbed by activated charcoal?
Water vapours. Stronger the intermolecular forces, easier to liquify, more strogly adsorbed.
Which gas is adsorbed activated charcoal?
Easily liquefiable gases like SO2,NH3 have greater value of critical temperature than elemental gases, i.e. N2,O2,H2 thus , readily get adsorbed.
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 of the following gas is absorbed most by activated charcoal?
Gases having higher critical temperature are easily liquefied. Hence in the liquid state they have greater force of attraction with the charcoal and therefore they are more easily adsorbed on the surface of the charcoal. Therefore, the gas which has the highest critical temperature is Methane or CH4 C H 4 .
What is activated charcoal adsorbed minimum?
Here , hydrogen has the minimum critical temperature, (-240∘C) hence, is adsorbed in minimum amount.
Which is more adsorbed on charcoal?
Because it is easily absorbed. So that in the given four gases, more absorbed in activated charcoal is sulfur dioxide (SO2 ). Therefore,the correct option is (A).
What is Physisorption give an example?
An example of physisorption is the adsorption of gases like hydrogen, nitrogen etc at lower temperature on the surface of adsorbent like charcoal. Physisorption depends on the surface area of the adsorbent. … For example, finely divided metals and porous substances have a large surface area.
Which gas is adsorbed strongly by charcoal so3 h2 n2 o2?
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 will be adsorbed more readily on the surface of charcoal and why NH3 or CO2?
a) NH3 has higher critical temperature than CO2 i.e. NH3 has greater intermolecular forces of attraction hance will be adsorbed more readily.
Which is maximum adsorbed by a charcoal N2 CO2 Cl2 O2?
The gas that can be strongly adsorbed by charcoal is NH3.
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 will absorb more gas a lump of charcoal or its powder and why?
Powdered charcoal will adsorb more gas because of its larger surface area than a lump of charcoal.
