Question

In physical adsorption the approximate heat energy evolved in kJ/mol is
(A)
20-40
(B)
40-60
(C)
60-80
(D)
40-400​

Answer 1

Answer:

The heats of adsorption in physisorption or physical adsorption lies in the range of 10−40 kJ/mol. It is less as compared to chemisorption as there is no chemical reaction involved in it.
