Question

Q. During adsorption
A \(\mathrm{T} \Delta \mathrm{S}\) is positive
B \(\Delta \mathrm{H}-\mathrm{T} \Delta \mathrm{S}\) is negative
c \(\Delta \mathrm{H}\) is positive
D \(T \Delta S\) and \(\Delta G\) become zero

Answer 1

Solution:
\(\Delta G=\Delta H-T \Delta S .\) Adsorption is spontaneous process \(\Delta G\) should be negative. Hence \(\Delta H-T \Delta S\) should be negative.
