In endothermic reaction with the increase of temperature adsorption will be :
Open in App
Solution
The correct option is C increase
The adsorption capacity may increase or decrease at higher temperatures, It all depends on the nature of the reaction and other controlling variables. If the reaction process is endothermic then adsorption may increase at higher temperature. This may be attributed to increased surface coverage at higher temperature, expansion and creation of reactive and active sites. Where the reaction is exothermic, then you may have a decrease in adsorption as at higher temperature. Therefore, we need to double check the enthalpy and entropy values at different temperatures.
