A) \[\Delta G\]is negative but \[\Delta H\]and \[\Delta S\]are positive
B) \[\Delta G,\Delta H\]and \[\Delta S\]all are negative
C) \[\Delta G\] and \[\Delta H\]are negative but\[\Delta S\] is positive
D) \[\Delta G\] and \[\Delta S\] are negative but \[\Delta H\]is positive
Correct Answer: B
Solution :
Adsorption is spontaneous process, so \[\Delta G\] = negative Adsorption is exothermic process, so \[\Delta H\] = negative In adsorpiton entropy decreases, so \[\Delta S\] = negative so \[\Delta G,\Delta H\]and \[\Delta S\] all are negative
