When the gas molecules or atoms are held to the solid surface by chemical bonds,the adsorption is termed as______________
Physisorption
Chemisorption
desorption
sorption
The material on the surface of which the adsorption takes place is known as ____________
adsorbate
absorbate
adsorbent
absorbent
_________have no interfaces.
Solids
liquids
gases
Water and kerosene
During dialysis
Only solvent molecules can diffuse
Solvent molecules, ions and colloidal particles can diffuse
All kinds of particles can diffuse through the semipermeable membrane
Chemisorption is generally ______________in nature.
Irreversible
reversible
temperory
endothermic
For adsorption of a gas on a solid, the plot of log x/m vs log p is linear with slope equal to (n being a whole number)
k
log k
n
1/n
Position of non-polar and polar parts in micelle is
Polar at outer surface but non-polar at inner surface
Polar at inner surface but non-polar at outer surface
Distributed all over the surface
Present in the surface only
_____________arises due to the fact that the surface particles of the adsorbent are not in the same environment as the particles inside the bulk.
Absorption
Adsorption
Sorption
Both adsorption and absorption can take place simultaneously,the _______________term is used to describe both the processes.
chemisorption
At the critical micelle concentration (CMC) the surfactant molecules
Decompose
Dissociate
Associate
Become completely soluble
