JEE Advance - Chemistry (2022 - Paper 1 Online - No. 10)
The correct option(s) related to adsorption processes is(are)
Chemisorption results in a unimolecular layer.
The enthalpy change during physisorption is in the range of 100 to $140 \mathrm{~kJ} \mathrm{~mol}^{-1}$.
Chemisorption is an endothermic process.
Lowering the temperature favors physisorption processes.
