Q.
The correct statement(s) pertaining to the adsorption of a gas on a solid surface is(are):
(i) adsorption is always exothermic.
(ii) physisorption may transform into chemisorption at high temperature.
(iii) physisorption increases with increasing temperature but chemisorption decreases with increasing temperature.
(iv) chemisorption is more exothermic than physisorption, however, it is very slow due to
the higher energy of activation.
Q.
Adsorption increases with increase in temperature in Chemisorption.
If true then enter 1 else enter 0.
Q.
Assertion :
N
2
is adsorbed on iron surface at
83
K which decreases rapidly with increase in temperature and at room temperature, practically no adsorption of
N
2
occurs. The adsorption, however, becomes significant at
773
K. Reason: At lower temperature, adsorption of
N
2
molecules on iron surface is physisorption and at high temperatures,
N
2
shows chemisorption of
N
atoms on iron surface.
Q.
Assertion :Physical adsorption increases with increase in temperature. Reason: Physical adsorption is an endothermic process.
