Question

The heat of adsorption in case of physisorption is approximately $20$ - $40kJmo{l}^{-1}$.

If true enter 1, else enter 0.

• A. 1

Answer 1

The correct option is A 1
For physisorption, the heat of adsorption is low and lies between $20$ to $40$ kJ/mol.
For chemisorption, the heat of adsorption is high and lies between $40$ to $200$ kJ/mol.
