A) Enthalpy is positive
B) Entropy decreases
C) Entropy increases
D) Free energy increases
Correct Answer: B
Solution :
[b] Entropy decreases When a gas is adsorbed on solid, its entropy decreases i.e entropy factor opposes the spontaneity of the process. Hence energy factor must favour, i.e. the process is exothermic, ie. \[\Delta H\]must be -ve i.e entropy decreasesYou need to login to perform this action.
