Which of the following is wrong :
Options
A.Enthalpy (numerical value) of physisorption is greater than that of chemisorption
B.Physisorption is not very specific but chomisorption is highly specific
C.Chemisorption takes place at relatively high temperatures
D.In physisorption generally multi–molecular layers are formed on the adsorbent
Solution
ᐃH = 20 - 40 kJ mol-1 for physisorption and ᐃH = 200 - 400s kJ mol-1 for chemisorption.
