Q. Adsorption is accompanied by
A) $\mathrm{\Delta}S$ of system is negative
B) Decrease in enthalpy of system
C) $T\mathrm{\Delta}S$ for the process is negative
D) All of the above
Explanation
(d)
In adsorption, due to forces of attraction, $\mathrm{\Delta}H$ is negative and as the particles came closer entropy of the system decrease, $ie,\ \mathrm{\Delta}S$ is negative, hence $T\mathrm{\Delta}S$ is also negative
