Test: Adsorption (Old NCERT) - Question 1

After the reaction is over between adsorbed reactants, it is important to create space for the other reactant molecules to approach the surface and react. The process responsible for this is known as

Detailed Solution for Test: Adsorption (Old NCERT) - Question 1

Desorption removes products from the surface to create space for other reactants.

Test: Adsorption (Old NCERT) - Question 2

Which of the following statements does not show correct difference between adsorption and adsorption?

Detailed Solution for Test: Adsorption (Old NCERT) - Question 2

Gases, liquids or solids can be absorbed on the solids surfaces.

Test: Adsorption (Old NCERT) - Question 3

Powdered substances are more effective adsorbents than their crystalline form because

Detailed Solution for Test: Adsorption (Old NCERT) - Question 3

Finely powdered substances have large, porous surface areas, hence act as better adsorbent

Test: Adsorption (Old NCERT) - Question 4

The term activation of adsorbent is used when

Detailed Solution for Test: Adsorption (Old NCERT) - Question 4

Activation of an adsorbent means, increasing the adsorbing power of the adsorbent. This can be achieved by, making their surface rough by mechanical rubbing or by chemical action. By doing so, it will increase the specific area of the adsorbent.

Test: Adsorption (Old NCERT) - Question 5

Which of the following is less than zero during adsorption?

Detailed Solution for Test: Adsorption (Old NCERT) - Question 5

Adsorption is a spontaneous, exothermic process with decrease in entropy, hence ΔG = -ve, ΔH = -ve and ΔS = -ve.

Test: Adsorption (Old NCERT) - Question 6

Which of the following is a property of physisorption?

Detailed Solution for Test: Adsorption (Old NCERT) - Question 6

Physisorption is non-specific in nature.

Test: Adsorption (Old NCERT) - Question 7

Which of the following statements is not correct about physisorption?

Detailed Solution for Test: Adsorption (Old NCERT) - Question 7

Physisorption does not require activation roergy since it takes place at low temperature.

Test: Adsorption (Old NCERT) - Question 8

The incorrect statement about physical adsorption is

Detailed Solution for Test: Adsorption (Old NCERT) - Question 8

Heat of adsorption of physical adsorption is quite low.

Test: Adsorption (Old NCERT) - Question 9

Which is correct in case of vander Waals adsorption?

Detailed Solution for Test: Adsorption (Old NCERT) - Question 9

vander Waals adsorption i.e. physisorption increase at low temperature and high pressure.

Test: Adsorption (Old NCERT) - Question 10

Adsorption is accompanied by the evolution of heat. So according to Le-Chatelier principle, the amount of substance adsorbed should

Detailed Solution for Test: Adsorption (Old NCERT) - Question 10

According to Le -Chatelier's principle exothermic reactions are favoured at low temperature.

Test: Adsorption (Old NCERT) - Question 11

Which of the following gases is least adsorbed on charcoal?

Detailed Solution for Test: Adsorption (Old NCERT) - Question 11

It has been found that more readily liquefiable gases are adsorbed more than permanent gases.

Test: Adsorption (Old NCERT) - Question 12

Which of the following is not characteristic of chemisorpiton?

Detailed Solution for Test: Adsorption (Old NCERT) - Question 12

Chemisorption forms unimolecular or one layer.

Test: Adsorption (Old NCERT) - Question 13

Chemisorption involves formation of bond between gaseous molecules or atoms and the solid surface for which high energy is required. Thus it is also referred as

Detailed Solution for Test: Adsorption (Old NCERT) - Question 13

Chemisorption is also referred as activated adsorption since it induces high activation energy.

Test: Adsorption (Old NCERT) - Question 14

Which of the following is not correct regarding the adsorption of a gas on the surface of solid?

Detailed Solution for Test: Adsorption (Old NCERT) - Question 14

Adsorption does not keep increasing continuously with increase in pressure.

Test: Adsorption (Old NCERT) - Question 15

Which of the plots is adsorption isobar for chemisorption?

Detailed Solution for Test: Adsorption (Old NCERT) - Question 15

The extent of adsorption first increases and then decreases with increase in temperature.

Test: Adsorption (Old NCERT) - Question 16

Which of the following statements is not correct for chemisorption and physisorption?

Detailed Solution for Test: Adsorption (Old NCERT) - Question 16

Chemisorption increases and physisorption decreases with rise in temperature.

Test: Adsorption (Old NCERT) - Question 17

In the adsorption of a gas on solid, Freundlich isotherm is obeyed. The slope of the plot is zero. Thus, the extent of adsorption is

Detailed Solution for Test: Adsorption (Old NCERT) - Question 17

x/m = kp1/n
In x/m = In k + (1/n) In P [∵ Slope = (1/n) = 0]
Thus, x/m = kp° ⇒ x/m = k

Test: Adsorption (Old NCERT) - Question 18

In Freundlich adsorption equation x/m = kp1/n, the value of n is

Detailed Solution for Test: Adsorption (Old NCERT) - Question 18

n is always greater than one.

Test: Adsorption (Old NCERT) - Question 19

Which of the following graphs would yield a straight line?

Detailed Solution for Test: Adsorption (Old NCERT) - Question 19

Equation of straight line for adsorption is log(x/m) = log K + (1/n) log p. Thus, plot between log(x/m) vs log p gives a straight line.

Test: Adsorption (Old NCERT) - Question 20

A graph is plotted between log (x/m) and P according to the equation x/m = kp1/n

Which of the following statements about this graph is not correct?

Detailed Solution for Test: Adsorption (Old NCERT) - Question 20

This is Freundlich isotherm not Langmuir.

Test: Adsorption (Old NCERT) - Question 21

At low pressure, the fraction of the surface covered follows

Detailed Solution for Test: Adsorption (Old NCERT) - Question 21

As (x/m) = kp1/n
At low pressure x/m ∝ p  (graph is nearly a straight line)
Thus, the reaction follows first order kinetics.

Test: Adsorption (Old NCERT) - Question 22

What is the role of activated charcoal in gas masks used in mines?

Detailed Solution for Test: Adsorption (Old NCERT) - Question 22

The poisonous gases present in coal mines are adsorbed on the activated charcoaL

Test: Adsorption (Old NCERT) - Question 23

Which of the following gases present in a polluted area will be adsorbed most easily on the charcoal gas mask?

Detailed Solution for Test: Adsorption (Old NCERT) - Question 23

Easily liquefiable gases like CO2, NH3, SO2, etc. are more easily adsorbed than the elemental gases like H2, N2, O2, etc.

Test: Adsorption (Old NCERT) - Question 24

Match the column I with column II and mark the appropriate choice.

Test: Adsorption (Old NCERT) - Question 25

Which of the following is application of adsorption in chemical analysis?

Detailed Solution for Test: Adsorption (Old NCERT) - Question 25

 All are the applications of adsorption.
