Which of the following incorrect match?

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

Explanation

`DeltaH=20-40 kJ mol^(-1)` for physisorption and `DeltaH=200-400s kJ mol^(-1)` for chemisorption.
