Which one of the following is correct for the adsorption of a gas at a given temperature on a solid surface?
Multiple Choice Options
- A H > 0, S > 0
- B H > 0, S < 0
- C H < 0, S < 0
- D H < 0, S > 0
Step-by-Step Verified Solution
(i) Adsorption of gas at metal surface is an exothermic process of H < 0
(ii) As the adsorption of gas on metal surface reduces the free movement of gas molecules thus restricting its randomness hence S < 0
(ii) As the adsorption of gas on metal surface reduces the free movement of gas molecules thus restricting its randomness hence S < 0
