Question

which of the following is not a favourable condition for physical adsorption​

Answer 1

Explanation:

Physical adsorption occurs at very low temperatures. With rise in temperature physisorption decreases. Therefore, among them high temperature is not a favourable condition for physical adsorption.

Answer 2

Answer:

Physical adsorption occurs at very low temperatures. With rise in temperature physisorption decreases. Therefore, among them high temperature is not a favourable condition for physical adsorption.

Explanation:

Physical adsorption is an exothermic process. It is favoured at low temperatures. This is in accordance with Le Chatelier's principle. With the increase in temperature, the extent of adsorption decreases.
