Which of the following factors affects the thermodynamics of adsorption?
Surface area of adsorbent
Nature of adsorbate
Temperature
Pressure
The thermodynamics of adsorption is influenced by temperature. Adsorption is an exothermic process, meaning it releases heat, which is reflected in the enthalpy change ( ). As temperature increases, becomes less negative or even positive, reducing the spontaneity of the adsorption process. Additionally, temperature affects the entropy change (), with higher temperatures leading to higher values. Thus, temperature plays a crucial role in the thermodynamics of adsorption, influencing both and, and consequently affecting the overall value for the adsorption process.
