Test Preparation on Surface Chemistry-I-Chemistry Test Series For NEET-2020

1.

The Langmuir adsorption isotherm is deduced using the
assumption

1The adsorption takes place in multilayers
2The adsorption sites are equivalent in their ability to adsorb the particle
3The heat of adsorption varies with coverage
4The adsorbed molecules interact with each other

Every adsorption site is equivalent and the ability of the
gas molecule to bound there is independent of whether the
neighbouring sites are occupied or not.

2.

If x is amount of adsorbate and m is amount of adsorbent,
which of the following relations is not related to adsorption
process

1A
2B
3C
4D

3.

In Freundlich Adsorption isotherm, the value of 1/ n is

1Between 0 and 1 in all cases
2Between 2 and 4 in all cases
31 in case of physical adsorption
41 in case of chemisorption

4.

In physical adsorption, the gas molecules are held on solid
surface by

1Chemical forces
2Electrostatic forces
3Gravitational forces
4Vander Waal's forces

5.

At the high pressure, Langmuir adsorption isotherm takes the
form
