Option: 1

Surface area of adsorbent

Option: 2

Option: 3



Option: 4


Answers (1)


The thermodynamics of adsorption is influenced by temperature. Adsorption is an exothermic process, meaning it releases heat, which is reflected in the enthalpy change ( \Delta H). As temperature increases, \Delta H becomes less negative or even positive, reducing the spontaneity of the adsorption process. Additionally, temperature affects the entropy change (\Delta S), with higher temperatures leading to higher \Delta S values. Thus, temperature plays a crucial role in the thermodynamics of adsorption, influencing both \Delta H and\Delta S, and consequently affecting the overall \Delta G value for the adsorption process.
