Question 1 :
The process of adsorption of hydrogen over palladium surface is called:
Question 4 :
The adsorption of a gas, on a solid surface, varies with pressure of the gas in which of the following manner?
Question 6 :
Which of the following characteristics is not correct for physical adsorption ?
Question 9 :
Assertion: Solids in finely divided state act as good adsorbents
Reason: Adsorption is a surface phenomenon.
Question 12 :
When the temperature is lowered and pressure is raised the adsorption of a gas on solid 
Question 14 :
Assertion: Soilds in finely divided state act as good absorbents.
Reason: Absorption is a surface phenomenon.
Question 16 :
Assertion: When $AgNO_3$ is treated with excess of KI, colloidal particles gets attracted towards anode.
Reason: Colloidal particles adsorb common ions and thus become charged.
Question 19 :
The volume of gases ${ H }_{ 2 },\ { CH }_{ 4 },\ { CO }_{ 2 }$, and ${ NH }_{ 3 }$ adsorbed by $1 g $ of charcoal at $288K$ are in the order:
Question 20 :
